RuntimeError: cannot connect to 'ldapi://%2fvar%2frun%2fslapd-IPA-LOCAL.socket':

Reason was the ipa-server-install tried to connect before DS was ready.

The patch adds waiting until DS is ready.

Patch attached.

Fraser can you please check if this fix works? I can't reproduce it.
Thank you, Martin^2.
