This reports uses of `File.exists?` and `Dir.exists?`, which were both
deprecated in Ruby and will eventually be removed in favor of
`.exist?`. Also fixes all existing uses of the deprecated methods.

Use Rugged's TagCollection#create instead of gitlab-shell's Repository#add_tag for better performance

Many users were experiencing timeouts when we only allowed
4 minutes before a timeout. A 15 minute timeout is more
than reasonable and prevents us from having to add a
configuration for this.

Fixes gitlab-org/gitlab-ee#246

gitlab-shell expects only one tab separator per key, and an SSH key with
a tab character in the comment, for example, would break things.

Closes #2970

Ths commit does next:

* When we remove project we move repository to path+deleted.git
* Then we schedule removal of path+deleted with sidekiq
* If repository move failed we abort project removal

This should help us with NFS issue when project get removed but
repository stayed. The full explanation of problem is below:

* rm -rf project.git
* rm -rf removes project.git/objects/foo
* NFS server renames foo to foo.nfsXXXX because some NFS client (think
* Unicorn) still has the file open
* rm -rf exits, but project.git/objects/foo.nfsXXX still exists
* Unicorn closes the file, the NFS client closes the file (foo), and the
* NFS server removes foo.nfsXXX
* the directory project.git/objects/ still exists => problem

So now we move repository and even if repository removal failed

Repository directory is moved so no bugs with project removed but
repository directory taken. User still able to create new project with
same name. From administrator perspective you can easily find stalled
repositories by searching `*+deleted.git`

This reverts commit 533f4cdf.

Before this it would fail because git hooks automatically prepend
things to the path, which can lead the wrong Ruby version to be called
in which dependencies are not installed.

To make sure that this is correct, the forked_merge_requests commented
out test that depends on this change was uncommented.

For that test to pass, it is also necessary to setup the mock server
on port 3001 under test_env.rb.
