feat: add CMD parse-genesis

[huichiaotsou]

Description

Closes: #246
Note: forbole/juno#30 and forbole/juno#31 will have to be merged

Add new command bdjuno parse-genesis to parse the genesis.json file

• users can specify which module in the genesis they would like to parse
• re-implemented HandleGenesis of staking mod to be run without a running node
• removed log.Debug() from HandleGenesis methods as parse-genesis is executed off a running node, avoiding log like:

{"level":"debug","module":"auth","time":"2021-11-16T15:28:37+08:00","message":"parsing genesis"}
{"level":"debug","module":"bank","time":"2021-11-16T15:28:39+08:00","message":"parsing genesis"}

• invalid arguments of module name are printed after the genesis is parsed
• Update doc: add bdjuno parse-genesis in the doc big-dipper-2.0-documentation#16

Hi @RiccardoM , I have changed it to ready for review. For the linter and test errors, it's because in juno I did 2 slight modification in order to separate parse cmd and parse genesis cmd, so I think those PR should be reviewed and merged first.

I think there is a lot of code duplication here that is not necessary
