Minor modification on dc-client side to skip validate_force_params
in order to allow upgrade with a group of subcloud (added feature)
as well as with a single subcloud (existing feature)
Test Plan:
1. Verify --force option can be used to create a strategy for a single
offline subcloud.
2. Verify --force option can be used to create a strategy for a group
of offline subclouds.
3. Verify --force option can be used to create a strategy for a group of
offline and online subclouds.
