Remco Bloemen 82c74ed21f Use CMD exec in Dockerfile
Without exec the `postgrest` process is not run with PID 1 (it
is a child process of the shell that starts it). This means
signals send to the docker (like `docker stop` or ^C) will
not be handled correctly.

However, Linux treats PID 1 as special and sets the SIGTERM
handler to ignore by default. It is also necessary to install
a SIGTERM handler.

This commit adds `exec` to resolve this problem, as per the
recommendation in the Dockerfile documentation:

Remco Bloemen e5d420b2db Gracefull exit on sigTERM
Like the sigINT that was already handled, postgrest
should gracefuly shut down on a sigTERM. This is a
common way of stopping processes, used amongst
others by docker.
