Merge #532: Fix CI. Move bitcoind tests to inner crate

8a07904 Add int tests to workflow (sanket1729)
4311760 Move bitcoind tests to inner crate (sanket1729)

Pull request description:

  This will allow us to have separate test dependacies and test CI only on
  stable. Ideally, we would want to have to a conditional dev dependancy
  but that is not possible currently

  Everytime `bitcoind` breaks with MSRV and we don't really need int tests with MSRV.
  Another issue is that testing this MSRV(2 years old) becomes a part of CI. When backporting fixes, we need to take care of making it pass. We need to support MSRV of old release(which is 2 + 2 = 4 years old). While our main code passes, the CI fails because we cannot build old bitcoind and we waste time figuring old versions.
