Runner + RPC

[zeeshanlakhani]

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)
