Test delegations with rosetta-cli

[ylecornec]

• run tests locally
• add support for delegation transactions to rosetta-cli. See https://github.com/coinbase/rosetta-sdk-go/pull/457
• add tests to the CI using the rosetta-go-sdk fork until changes are merged upstream. See Add rosetta-cli delegation tests #12373.
• Use new version of rosetta-cli after changes are merged upstream.

@Sventimir this is an issue in review. Does that mean that you believe that #12373 is sufficient to close this issue? Do we really need to wait for upstream? What is the ETA on this task?

[Sventimir]

@robinbb There's also PR ro rosetta-sdk-go, which the PR you mentioned depends on. I think we don't have to wait for Coinbase to integrate our changes, though, as we can build rosetta-cli with updated SDK for our internal testing. Actually this is what #12373 does for the moment. So I think as soon as CI issues that block merging of #12373 are fixed, we can merge and close this issue. No need to wait for the upstream indeed.

I extracted the update our tests when our changes are accepted upstream to a separate issue: #12509.
