Remove 'monkeysphere' support from 'users' role

Support for 'monkeysphere' GPG keys on user accounts will be migrated to
a separate, non-common role similar to 'sshkeys', most likely combined
with current 'monkeysphere' role.
Remove various parts of 'users' role

This patch removes support for:
  - creation of custom directories on user accounts;
  - management of user websites using restricted git-shell accounts;
  - restricted sftponly accounts;
Support for git-shell and sftponly accounts will be reintroduced in
separate roles.
