Implement remaining transaction type proxies in coreAccessor

[renaynay]

• Implement each transaction type proxy inside of core_access.go
• expose these methods via higher level Accessor interface and have Service proxy to the accessor's impl of them
• expose via RPC

So, from my understanding, the transaction types we need to proxy are sdk.Msg's which are defined in the cosmos-sdk modules. For example, bankypes.NewMsgSend for our ca.Transfer.

Is this correct @renaynay ? I cannot find any comprehensive list of all Msg types supported by all standard modules, and it looks like we don't need all of them (unsure though). So I would start with the staking types first as you linked me. Any other ones, or is that all for now?

We need:

TypeMsgUndelegate                = "begin_unbonding"
TypeMsgCancelUnbondingDelegation = "cancel_unbond"
TypeMsgDelegate                  = "delegate"
TypeMsgBeginRedelegate           = "begin_redelegate"
