Set short ANSIBLE_SSH_CONTROL_PATH_DIR for all ceph roles

We set ANSIBLE_SSH_CONTROL_PATH_DIR to deal with permissions
issues. Bug 1885917 was introduced because it was set to a
variable which can make the path too long for a Unix domain
socket. We can fix it by hard coding it to something short
which will not vary.
