Move blockGasLimitContract to AuRa params and rename it

[vkomenda]

This is a backport from openethereum#10928.

The new name of the parameter is blockGasLimitContractTransitions. @varasev, @phahulin, please use the new name in spec files.

@phahulin, @varasev: If I'm reading the code correctly, you also can't specify a single contract address anymore. It has to be a map of block number to contract address.

Yes, we use the map anyway.

I'd propose to merge this after openethereum#10928 is finished because there can be other changes as far as I understand.

Ok, let me first test the new aura-pos with the changed param. If that works fine with posdao-test-setup then OK.

[varasev]

That works fine.

Sorry for merging early!
I think it's pretty independent of the other potential changes in the upstream PR, though.

Yes, it is. I think we will have to add the same changes in our aura-pos when that PR is merged to upstream.
