Added system hooks messages for renaming and transferring a project

This is work in progress but I wanted to get some feedback on it in case there is something I've missed or a better way to do it.

As the title says when a project is renamed or transferred to another group a system hook message is generated.

Currently adds a couple of extra properties to the standard project system hooks messages.

old_path_with_namespace - The old path of the project so we can see what has been renamed / transferred
changed_at - The time that change took place

My main concern is if there is a better way of doing this than passing the extra_data variable into the system hook.  Would it be better to extend the project model with these 2 items as transient properties as I doubt they would need to be saved to the database?  The other 

I've also seen, but can't find, someone talking about the emails sent when a project is renamed or transferred doesn't reference the original project path so if you have similarly named projects then you might not know what has been moved.  I think the extra_data (or however it is best to implement this) would allow the extra information to be sent in emails.

This ensures Rails and Sidekiq transactions are split into the series
"rails_transactions" and "sidekiq_transactions" respectively.

This removes the need for any tags to differentiate between Sidekiq and
Rails statistics while still being able to separate the two.

This makes it easier to see where time is spent without having to
aggregate all the individual points in the method_calls series.

This will be used to store/increment the total query/view rendering
timings on a per transaction basis. This in turn can greatly reduce the
amount of metrics stored.

Fog has a local storage provider, which can be use to copy backups to locally mounted cifs / nfs / smb shares. This MR adds documentation to doc/raketasks/backup_restore.md in response to #3387.

@stanhu I found some time tonight and was able to get this started earlier than I initially expected, glad I could contribute.
