On cli startup, log a info line with basic info

And 'info' level log the exit code.

For ex:

[2019-05-30 11:17:51,249 28223 I] ansible_galaxy_cli.cli.galaxy run:236 - \
  exe="/home/adrian/venvs/mazer040test/bin/mazer" version=0.5.0 \
  config_file="/home/adrian/.ansible/mazer.yml" \
  collections_path="/home/adrian/.ansible/collections" \
  server=http://localhost:8000 action=install

Fixes ansible#267
