projectile-discover-projects-in-directory is not interactive as documented

[memeplex]

Expected behavior

The documented behavior:

To add a project to Projectile’s list of known projects, open a file in the project. If you have a projects directory, you can tell Projectile about all of the projects in it with the command M-x projectile-discover-projects-in-directory.

Actual behavior

The function is not M-x-accessible and it's not defined as (interactive). Besides it takes a mandatory argument:

(defun projectile-discover-projects-in-directory (directory &optional depth)
  "Discover any projects in DIRECTORY and add them to the projectile cache.

If DEPTH is non-nil recursively descend exactly DEPTH levels below DIRECTORY and
discover projects there."
  (if (file-directory-p directory)
      (if (and (numberp depth) (> depth 0))

This was tested in revision 7f64570 and in tag v2.5.0.

• M-x projectile-discover-projects-in-directory

My bad, I'm sure I intended for this to be an interactive command. Perhaps we changed this at some point accidentally. That is easy to fix.
