Ability to create snapshots for multiple dbs from a single call for on_demand_snapshot function

[aburkhart13]

Is your feature request related to a problem? Please describe.

When using the following call for dbs, it is required to perform a call for each db or use for loop and call the function for each snapshot
https://rubrik.gitbook.io/rubrik-sdk-for-python/v/devel/data-management-functions/on_demand_snapshot#vmware

Describe the solution you'd like

I would like an option to allow for multiple databases to be selected within the same call either with a direct reference with the db name or using a wild card to perform for a group of databases.

Describe alternatives you've considered
Currently this can be accomplished with a for loop
