Summary:
While testing with the fb-eden rpm installed, I hit some integration
test failures. These were caused by the integration tests picking up the
default post-clone hook configuration.
This diff changes our existing `systemConfigDir` option (which defaults to
`/etc/eden/config.d`) to `etcEdenDir` (which defaults to `/etc/eden`) and
adjusts the code that consumed `systemConfigDir` to construct the effective
value by computing `etcEdenDir + "config.d"`.
Doing this allows us to also default the `repoHooks` path to be
`etcEdenDir + "hooks"` rather than just hard coding `/etc/eden/hooks`.
The result of this is that our integration tests will now pass when `fb-eden`
is installed, because they override the `etcEdenDir` option and isolate their
`edenfs` processes from the globally installed configuration.

Summary:
I don't know that I'm happy with the name; it started out as
just a helper wrapper to apply interpolation, but grew a bit to better
encapsulate how we access the config from the eden server.
This is a utility class that I'd like to use in place of the raw boost
property tree in our ClientConfig code.
It encapsulates the underlying property tree and provides a couple of simple
methods; one for loading data from a config file and one for looking up
a configuration value.
The configuration value lookup will replace tokens of the form `${KEY}`
with the value of `KEY` from its internal replacements dictionary.
This mirrors the interpolation handling that we do in the equivalent python
code for the eden client.
