Convert to ports (#5)

* Remove erlexec dependency

* feat: async verify worker has started

* test: move infinite to script

* fix: timeout response

* fix: unix compile [Closes #169398412]

* feat: allow database patterns as worker param

This allows us to expand paths in an application, which is not possible from the configuration file.

* OTP 22 compatible with Elixir 1.7-1.10

* Install make on CI server

libmagic-dev contains magic.h

Fix this error:

  ** (Mix) Could not compile with "make" (exit status: 2).

* Fix make install

* Fix plurality

* Fix credo warning

* Allow multiple error messages

OS X and Linux return different errors messages.

* Allow named GenServer processes

* Types

* Disable test broken in ci

Works locally, not in CI.

     ** (EXIT from #PID<0.1672.0>) shutdown
