Bad use of method 'inspect' causes bool values not to apply.

[pazmarianoj]

Based on gitlab documentation and feedback from support, I realized that the boolean values passed to the gitlab.rb file are not being parsed properly due to a misplaced quotes. Gitlab expects bool values to be passed as is, without any quotation.
Usage examples:
postgres['enabled'] = 'false' -> Service still running visible via gitlab-ctl status
postgres['enabled'] = false -> Expected behaviour.

Main reason: https://ruby-doc.org/core-2.3.0/String.html#method-i-inspect

numify(v).inspect
