feat(indy-test-ledger): add helper class for indy ledger
Browse files Browse the repository at this point in the history 
- Add `IndyTestLedger` class to setup test indy ledger for testing purposes.
- Add functional tests for new test ledger class.
- Minor fix in cleaning up sample indy test ledger.

Peter's changes:
1. Rebased onto upstream/main as of 2024-01-21 which was a bit of a
challenge on account of this  being quite old (110 commits behind)
2. Meaning that there's a chance that I messed up some of the conflict
resolutions in a way that is sub-optimal, please forgive if this is the
case!

Depends on #2861
