Token holders able to batch claim delegation reward

[lxfind]

Currently a SUI token holder will have to send a transaction per epoch for each epoch they have delegated.
Ideally we want to enable a SUI token holder to do that by one action. This can either be done through UI trick which does N transactions under the hood, or we support a function that supports passing in a vector of epoch record objects so that it can claim multiple epochs in one transaction.

Depends on #492 if we choose the latter option.

There is a new and more elegant design proposal which can affect the implementation if the math works out for the new design.
