feat(OSD-19388): use backplane and enable new flow

[typeid]

What?

• Moves CAD to use backplane for the old flow
• Enables CAD to get cloud credentials through the new flow (also via backplane)

Cleanup:

• Renames v1 to cmv1

Why?
https://issues.redhat.com/browse/OSD-19388

Notes: this PR is waiting for openshift/backplane-cli#267 which adds logic to allow CAD to re-use backplane-cli's bpcloud.GetAWSV2Config logic.

Tests:
Tested the following scenarios locally:

• changed trust policy to not allow jump, results in CAD setting LS
• delete installer role, results in CAD setting LS
• delete installer and support role, results in CAD setting LS
• delete just support role: results in CAD setting LS
• pure OCM errors don't result in LS
• Full CAD CHGM run of the new and old flow.

[typeid]

For testing with the local backplane-cli build. This will be changed to the backplane-cli version once openshift/backplane-cli#267 merges.
