Port changes to rosetta-sdk-go to our own fork

[kantp]

We are currently using a modified version of rosetta-sdk-go for testing of constructing transactions invoving delegations. Those modifications are currently in https://github.com/ylecornec/rosetta-sdk-go, but we want to have them in https://github.com/MinaProtocol/rosetta-sdk-go.

@kaozenn said that https://github.com/MinaProtocol/rosetta-sdk-go seems to have some changes that are incompatible with the main repository at https://github.com/coinbase/rosetta-sdk-go, so the first task here will be to look at whether those changes are still relevant.

Indeed, https://github.com/MinaProtocol/rosetta-sdk-go is no longer compatible with the main repository. There are 3 commits made in August 2020 and the repository seems to not have been updated ever since. It can be realtively easily rebased, but I think MinaProtocol/master should always reflect the main-line master. Therefore I'll rename the main branch and rebase it in case anyone needed it still (which I don't think is likely). Then I'll sync our master with the main-line. Finally, I'll clone Yves-Stan's work to yet another branch in our repo.

In fact it seems that these commits were actually integrated into the main-line, albeit with some modifications.

I renamed the stale master branch to master-old. I then set master to follow the main-line repository. Finally I cloned Yves-Stan's branch as pallas_signer_stake_delegation. It follows Yves-Stan's branch, but that is unlikely to change in the future. However, we might need to make some changes to it in case Coinbase requests it. In that case we won't be able to change Yves-Stan's code. I'm also not sure if we'll be able to replace his branch with ours in the existing PR. Maybe it'd be the easiest to close that PR and reopen our own?

[kantp]

Yes, that sounds like a good idea!

The new PR meant to replace the one by Yves-Stan: coinbase/mesh-sdk-go#464.
