Start first enumeration immediately

Previously, we would wait for ten seconds before starting an
enumeration. However, this meant that on the first startup (before
we had run our first enumeration) there was a ten-second window
where clients would immediately get back a response with no
entries instead of blocking until the enumeration completed.

With this patch, SSSD will now run an enumeration immediately upon
startup. Further startups will retain the ten-second delay so as
not to slow down system bootups.
