[FEATURE REQUEST] Allow Public Groups for Polymorphic Fields (e.g. UserOrGroupId)

[6andrey]

While, I appreciate the documentation Can I override the default query for the User or Group objects?, there is a valid use case for Public Groups (not Queues) to be mapped.

For example, there is a requirement to insert AccountShare records. The query below is used:

Select AccountAccessLevel, CaseAccessLevel, OpportunityAccessLevel, AccountId, UserOrGroupId$Group From AccountShare

The external Id is set as:

"externalId": "AccountId;UserOrGroupId"

Please note the migration works fine for the SFDMU release up to at least 4.23.2. Then, after the #579 fix, the Group records are filtered by Type = Queue only, which leads to exclusion of any Public Groups.

Would be nice to be able to select if Groups can be:

• not filtered at all (as in version 4.23.2 or earlier)
• filtered by Type = Queue
• filtered by Type = Regular
