add integration test for aid to join multisig

[daviddm]

This PR includes multisig test join and illustrates the problem in #227.

The integration test creates a multisig-group with 2 members and threshold 1.
Member 1 adds a new member(member3) to the group and does a double rotation for the new member to be able to join and add the end-role by himself.

Cross-posting here, I tested this against this PR WebOfTrust/keria#254 and it was successful. Once 'keria:latest' is updated, this test should pass.

Also, if we were to pull WebOfTrust/keria@caad67b and patch 0.1.x of keria, we could merge this without having to upgrade to keria 0.2.x.

@daviddm if you would like to rerun these checks, KERIA:latest should have the fixes needed:

Although I'm aware that the cherry pick option that @lenkan points might be preferred at this point.

@daviddm @2byrds I have rebased the branch and re-ran the test, it passes now.
