HTTPClient initializes with wrong keystone credentials if master node wasn't working after revert

[Dennis Dmitriev]

If 'KEYSTONE_PASSWORD' variable was changed, then the following issue might appear:

- HTTPClient initializes with new 'KEYSTONE_PASSWORD' at the start of the test;
- when master node hung after reverting a snapshot, it is restarted and wait until '_fuel_web.client.get_releases' gets the list of releases

The issue is that the reverted master node has a default keystone credentials while '_fuel_web.client.get_releases' tries authorize to keystone with new 'KEYSTONE_PASSWORD' and failed.

    Try change Keystone credentials before using protected Nailgun API

    If 'KEYSTONE_PASSWORD' changed, HTTPClient initialazes with a new
    password. Nailgun API cannot be used on reverted environment until
    Keystone password be changed from default to new one.

    - use _wait() until Keystone password be changed
    - check if reverted snapshot version is 5.x.x and use apropriate
    fuel cli options for this version.
