Create profile::git_webhook to abstract away the details

Prior to this commit there were two possible webhooks
 - zack/r10k webhook
 - code manager

I moved these two profiles under git_webhook and choose the correct
one based on the version of PE being used.

As a safety hatch, I provide the $force_zack_r10k_webhook param
on profile::git_webhook in case someone needs to continue using it
instead of code manager.
