Fix keypair creation

Use novaclient for creation of keypair instead of openstack client in
devstack plugin, because the latter is not compatible with
nova microversion 2.1

Also, specify explicitly Nova API version in manila wrapper over
novaclient that is used by Generic and Windows drivers.

Also, revert back amount of tempest threads for Ci jobs to avoid job
timeout failures.

Also, fix raise of SnapshotBuildErrorException in Tempest plugin.
Tempest tries to raise exception SnapshotBuildErrorException from wrong
place. It should use "share_exceptions" instead of "exceptions".
