Add option in `config.yml` to easily change default staking denom

[lumtis]

The current docs gives indication to modify the staking token denom: https://docs.starport.com/kb/genesis.html#change-values-in-modules

However, for many apps that use a single token for all module usages, different part of the genesis must be checked and modified

We should provide an option to easily modify these options in one place and set the "default token denom"

In config.yml

default-denom: "spn"

Would automatically set in the genesis:

genesis:
  app_state:
    staking:
      params:
        bond_denom: "spn"
    crisis:
      constant_fee:
        denom: "spn"
    gov:
      deposit_params:
        min_deposit:
          - "amount": "10000000"
            "denom": "spn"
    mint:
      params:
        mint_denom: "spn"

Arguably, this looks more like a command, rather than a separate config. Perhaps,

starport chain config denom spn

Could modify config.yml in all the right places (and make necessary checks).

The thing I don't like about this being a separate config is that information can go out of sync (default-denom and configs in the genesis).

Thanks problem solved was also facing same challenge. Can you assist with more commands to customise the config file eg . zero gas fees i.e send from coin wallet to wallet free with no transaction fee (is this possible?)
