Initial implementation of the hook feature

The current implementation is modular and allows users to define hooks
in several ways:
  * Use one of the built-in hook types (currently only 'exec')
  * Define their own Hook classes inside ~/.config/oxidized/hook

Exec hook type runs a user defined command with or without shell. It
populates a bunch of environment variables with metadata. The command
can either be run as synchronous or asynchronous. The default is
synchronous.
