Runner + RPC (#203)

Includes:

* restructure main
* separate logger interface for rolling files vs stdout (all async
nonblocking)
* tarpc (non-proto) Server/Client implementation to "speak" RPC to the
Runner
* db initialization cleanup
* Lots of channel scaffolding and reliance
* CLI output with tables and diagnostic error(s)
* Make resolve take an async closure and work via async_recursion
* ability to run homestar runner/server in daemon mode
* docker cleanup and now having an entrypoint w/ homestar start
* cargo-nextest configuration
* CLI / e2e RPC tests in serial mode
* build.rs for compile-time pending migrations (if not run previously)
* handle ports correctly for parallel tests
* prep for worker set and delayqueue
* ARCify your demons
* proper use of spawn and block_on within a Runner's (tokio) runtime
* rwlock for linkmap (cross-thread)
