Return 40x error codes if branch could not be deleted in UI

### What does this MR do?

This MR makes `BranchesController` return the proper status code in case of a failure to delete a branch.

### Why was this MR needed?

Deleting a branch would always return status 200, even if the branch could not be found or deleted for some reason. This was confusing because while trying to debug an issue with encoded slashes, it looked like the deletion was successful when it had failed.

### What are the relevant issue numbers?

This issue was uncovered in #1804

Add ref switching support for graphs

It is now possible to view contributor and commit statistics for
refs beyond the default branch. While the Git ref already was part of
the path it has not been used before.

Additionally, the code in RefsController#switch has been slighliy
refactored since it would have become confusing with additional if-else
branches added.

This reverts commit af44c650.

Add Irker service configuration options

### What does this MR do?

This MR makes a number of hard-coded Irker parameters configurable in the service settings: Irker server host, port, and default IRC URI. It also removes the "max recipient" limit since the recipient list is configurable only by the project owner, and it makes no sense to update the limit when it is implied in the recipient list already.

### Why was this MR needed?

The existing service assumed that gitlab.com was running an Irker daemon on `localhost` when it was not. Using Irker on gitlab.com thus did not work at all. This MR allows users to provide their own Irker daemons.

### Are there points in the code the reviewer needs to double check?

My main concern is whether allowing a user to specify the server/port combination would have security implications for a host. Given that HipChat and Slack allow users to do this, I didn't think this was doing anything novel.

### What are the relevant issue numbers?

* Closes #1713
* Closes #1714
* Closes gitlab-com/support-forum#139

Allow user to be blocked and activated via the API

When authenticating against LDAP if a user has been disabled in LDAP they can no longer log on to the website or commit over http(s) but will be able to commit using any ssh keys.  This functionality allows us to look for users in GitLab that no longer exist in LDAP and disable then in GitLab.

Changed the reference from gitlab cloud to gitlab.com because it was outdated.

This one confused me a bit because i was searching for gitlab cloud and the first thing i saw: "It's gone and now it's gitlab.com"
So to prevent anyone other than me from being a bit puzzled this little change should help

Fix redirection to home page URL for unauthorized users

Redirection to the home page URL was broken by changing the target for
`root_url` from `DashboardController` to `RootController` in
94d3c143. This regression was introduced
in the 7.12.0 release.

Fixes #1916.
