Adds stripped down ODL CSIT deployment

Adds stripped down ODL CSIT deployment

Introduces new (hidden) cli option to change composable env config.
This parameter then will use the provided file, for example,
csit-environment.yaml instead of the typical opnfv-environment.yaml.
The effect is using less services required for ODL CSIT snapshots.
Note: this will not work with perf options, but those are not required
currently for ODL CSIT.

CSIT also does not need ceph, so providing a new deploy option to
allow disabling it.
