execution-service: add new subcommand execute

This subcommand starts a single node remote execution service honoring
the just native remote protocol.

If the flag --compatible is provided, the execution service will honor
the original remote build execution protocol.

New command line args supported by this subcommand:

-p,--port INT: Execution service will listen to this port. If unset,
 the service will listen to the first available one.

--info-file TEXT: Write the used port, interface, and pid to this file
  in JSON format. If the file exists, it will be overwritten.

-i,--interface TEXT: Interface to use. If unset, the loopback device
 is used.

--pid-file TEXT Write pid to this file in plain txt. If the file
  exists, it will be overwritten.

--tls-server-cert TEXT: Path to the TLS server certificate.

--tls-server-key TEXT: Path to the TLS server key.
