init: added check for ldap

[vitoravelino]

Added a new check to verify if the ldap instance is ready before running velum dashboard in order to avoid a connection error when creating a new user.

I've realized that I added the check to the wrong file. It should be checked in the run file that belongs to the velum-dashboard container and not in the init that belongs to the dashboard initContainer.

@mssola, @flavio can we merge this?
