Allow for list when using deleting/removing CumulusCI orgs (`cci org remove` and `cci org scratch_delete`)

[Julian88Tex]

Feature Type

I'm interested in functionality that solves a current problem or limitation in how CumulusCI works.

Does your feature request solve a current problem?

Often I need to remove or delete multiple orgs. Currently, the only way I know how to do this is to string them together in commands or create some local custom script.

Describe the solution you'd like

It would be nice if you could just list orgs comma separated for cci org remove and cci org scratch_ delete commands). Example: cci org remove org1,org2,org3.

Describe alternatives you've considered

No response

Additional context

• May also be nice to be able to do something similar for more complex actions like cci org flow run but I can also see that as getting out of hand and scale up issues.
• It's probably a good idea to always require a confirmation prompt when deleting multiple orgs if that isn't already the case.
