Summary:
Now that Rust macros can be `use`d like normal symbols, `stats` can
simply import the `lazy_static!` macro without requiring its users to do it.

Summary:
Default ServiceType is ServiceType.Any, so it might go to master in a master
region. This diff changes it.

Summary:
Sharding filenodes by path should stop us knocking over databases -
make it configurable.

Summary:
We can already flatten a single XDB server with filenodes traffic, and
do if we start up a server instance without a warm memcache. This is only going
to get worse in the future.
Start the process of sharding across multiple servers. For now, we can only
deal with shard size == 1, but this code should be ready to handle shard sizes
greater than 1

Summary:
As per the comments added - MyRouter setup is such that it starts inside a tupperware container together with the binary that will be using it. This means that by the time the binary wants to use the MyRouter connection the MyRouter instance might not be ready yet. In order to mitigate this effect the myrouter::Builder will attempt to make a "Select 1" query and retry it with a backoff for a max of 2 min or until the connection is actually established.
Unfortunately the `queries!` macro had to be moved inside the `macro` module in order to make it usable from inside `myrouter` module, see this: https://stackoverflow.com/questions/31103213/import-macro-from-parent-module
