The method hmy_estimateGas does not exist/is not available
The sdk is aiming to support. However the blockchain rpc is not. To work around this problem, please use specify gasLimit and gasPrice amount manually.

Actually, the function of "hmy_estimateGas" has implemented, see this: https://github.com/harmony-one/sdk/blob/4b7d95c429433d29f627e0156aaf8fc695bc05fe/packages/harmony-contract/src/methods/method.ts#L158
the problem is we don't have a function in core-protocol...I am going to fix that.
Expected behavior After calling hmy_estimateGas, it should work.
