Jean-Philippe Evrard e5622adc43 Speed up gate: avoid gathering facts more than necessary 
This commit adds a gather_facts variable in the playbooks, which
is defaulted to True. If run_playbooks.sh is used, this commit adds
"-e gather_facts=False" to the openstack-ansible cli for the playbook
run. Everything should work fine for deployers (because there is no
change for them), and for the gate (because fact caching is enabled)

It should speed up the gate by avoiding the long "setup" task cost for each host.
Instead it does the setup to the appropriate hosts, at the appropriate time.
