Sahara DEBUG writes a lot of logs via neutronclient

[Andrew Lazarev]

Steps to reproduce:
1. Set log level to DEBUG
2. Start cluster in lab with a lot of security groups

Observed behavior: log is full with information from neutronclient

Workaround: 'neutronclient=INFO' setting resolves the issue

I figured out that logs come from quota limits check. To check quotas we are retrieving all floating IPs, security groups and ports.

    Disable neutron DEBUG logs

    We are retrieving ALL neutron objects to check quotas. This could
    lead to logs flooding.

    Ideally quotas usage check should be done on neutron side, but it
    looks there is no way to do that. Horizon retrieves all neutron
    objects too.

    So, just disabling DEBUG for neutron client.
