nscd should be disabled before sssd is configured/started.

If not then sssd spits out a warning message:

sssd: nscd socket was detected.  As nscd caching capabilities may conflict
with SSSD, it is recommended to not run nscd in parallel with SSSD

Stop nscd before configuring sssd so we don't confuse our users.
