Ceph python bindings are now available from pypi, so they can be
installed within a venv. Previously we were relying on the bindings
being installed via an apt package and symlinking out of the relevant
venvs into site packages.
This commit also includes a revert for the commit that introduced the
symlinks:
Revert "Symlink ceph libraries out of venv"
This reverts commit a0ab6f7a6efea1dabf5ac006f766c17596a0d10b.
