Summary:
For the redirect subcommand I wanted to automatically tabulate
some data to display it, so here's a little helper function.
The intent is that we pass a list of dictionaries with the data and let
the tabulate function render it for human consumption.
That same set of dictionaries could also be passed to a json serializer
for machine readable output (out of scope from this diff).
The tabulated data is intentionally limited in this current form:
* We make a run through and compute the max width of each column
* A simple header_labels map can be used to provide more human
readable versions of the dictionary keys as the column headers
* A missing header lable defaults to the uppercased version of
the dictionary key for that column
* Cell contents are all left aligned in their respective cell

Summary:
The `FieldConverter<bool>` code previously relied on `folly::to<string>()` for
all arithmetic types, including `bool`. Unfortunately `folly::to<string>()`
returns `"1"` and `"0"` for booleans, which isn't terribly human-friendly.
This updates the code to explicitly return `"true"` and `"false"` as the
output for converting boolean values to strings.

Summary:
The `ConfigSetting` code previously used `folly::to<string>()` to convert
field values back to strings for debugging. However, this only works for
values that actually are supported by `folly::to()`
This changes the code to use the `FieldConverter` to perform the conversion
back to string. The `FieldConverter` class now contains the logic for doing
conversion both from strings and back to strings.

Summary:
Add a `stringToDuration()` function to parse a string into a
`std::chrono::nanoseconds` value.
Strings are parsed as a sequence of `[number] [unit]` pairs.
For instance:
`1m30s` --> 90 seconds
`5s10ms` --> 5010 milliseconds
`1d3h10m` --> 1 day, 3 hours, 10 minutes (1630 minutes total)

Summary:
Update the `FieldConverter` code to support parsing any arithmetic type
(integers and floating point) using `folly::to<T>()`. Also change the `bool`
conversion implementation to use the same code.
This does change the `bool` implementation to accept any string accepted by
`folly::to<bool>(string)`. The old code only allowed `true` and `false`. The
new code allows other strings: `yes`, `no`, `y`, `n`, `0`, `1`, `on`, `off`
This also makes the implementation more efficient by eliminating some
unnecessary string copies and avoiding throwing exceptions internally on
error.

Summary:
Add a thrift call to get the current config settings.
My primary use case for this method at the moment is to make it possible to
build integration tests that check the config behavior. However in the future
this will probably also be useful for building CLI commands to report the
current config values to allow debugging if there are ever issues. This API
can also be used to force EdenFS to immediately reload the config from disk.

Summary:
Change the `ReloadableConfig::getEdenConfig()` method to accept an enum to
control whether it should reload the configuration, rather than the simpler
bool that it used previously.
The primary motivation for this is to allow us to force a reload to occur in
unit tests and integration tests, even if this operation would otherwise be
within the normal reload throttling time limit.

Summary:
With systemd integration enabled, if edenfs is running, or if edenfs' systemd service is active, `edenfsctl start` does nothing. This behavior differs from `edenfsctl start` with systemd integration disabled, and can cause `edenfsctl restart` to think that it successfully started edenfs.
Make `edenfsctl start` fail if edenfs is running and healthy, or if edenfs' systemd service is active (yet edenfs is unhealthy).

Summary:
get_edenfs_start_cmd checks if edenfs is already running, and fails if it is. Most of the time, this check is redundant. This function is effectively called in five places:
* `edenfsctl start`
* `edenfsctl clone` if not running
* `edenfsctl restart` (`_graceful_restart`) with takeover=True
* `edenfsctl restart` (`_start`) if not running
* `edenfsctl restart` (`_finish_restart`) after stopping edenfs
The check is only necessary in one of these places (`edenfsctl start`). Move the check.
This refactor will allow us to run the check if systemd is enabled without duplicating code.
This diff should not change behavior (ignoring unimportant race conditions).

Summary:
D15683387 introduced manifest for libcurl and used cmake instead of autoconf
(rationale: having cmake build curl would make it easy as we want curl to build
on windows and macos).
if libcurl finds ldap.h, then it builds with ldap enabled.
On my devserver, ldap library is not installed, and thus libcurl builds without
it, and links with FBOSS binaries fine.
In sandbox, ldap seems to be installed, thus libcurl builds with ldap. However,
linking fails for FBOSS binaries as those don't link against ldap - FBOSS does
not depend on ldap.
Thus, we need a way to configure libcurl with ldap disabled. [cmake.defines]
CURL_DISABLE_LDAP=OFF, does not quite do it. Thus, am going with autoconf, with
args --disable-ldap for now for Linux and cmake for non-Linux environments.

Iproute2Builder copies include/* from build to install directory, it does not

may not find).

Summary:
systemctl has some problems for Eden. For example:
* With Restart=on-failure, 'systemctl start' reports that the job failed when the first failure occurs. 'systemctl start' does not wait for retries to finish. This means 'eden start' can fail despite edenfs starting successfully.
* If the service fails to start, 'systemctl start' prints a suggestion to use journalctl, even though journalctl is broken and is not even used by fb-edenfs@.service.
* If 'systemctl' can't connect to systemd, it prints a generic message such as "Failed to connect to bus: Connection refused" which the Eden CLI can't easily detect and customize.
For 'eden start', instead of using systemctl, talk to systemd using its D-Bus API (via pystemd [1]). This automatically solves the journalctl message problem, makes it trivial to customize certain errors, and will let us solve the Restart=on-failure problem in the future.
Aside from changing some error messages, this diff should not change behavior.

Summary:
Update the EdenServer::unmountAll() code to make sure to keep a shared_ptr
reference to the EdenMount while the EdenMount::unmount() call is running.
Previously this could cause use-after-free errors due to the EdenMount
object being destroyed while the `unmount()` logic was still running. In
particular, as soon as we call `privhelper->fuseUnmount()` the
fuseCompletionFuture could complete in a different thread. The
fuseCompletionFuture's callback (normally the lambda inside
`EdenServer::mount()` which triggers the call to
`EdenServer::mountFinished()`) may have the last outstanding shared_ptr
refcount to the `EdenMount` object. When it finishes in this other thread
it will then destroy the EdenMount, possibly before the
`EdenMount::unmount()` logic has completed.
