feat(cli): Specify client.toml variables (gas, gas-prices, note, etc)

[Reecepbcups]

Closes #518

CI Failure note

The linter upgraded overnight... 95% of the issues are in the oracle and price feeder - which are being removed anyway in another PR

Feature

Reads from the client.toml file to get custom defined variables. This includes:

• gas
• gas-price
• gas-adjustment
• fees
• fee-account
• note (memo)

Logic

• When set in the config, it auto populates by setting the env of said command for that transaction.
• If a user has a local env set, it will override the config
• junod config gas 1000000 to add in all the custom configuration options
• If you set gas-prices, it will clear fees. If you set fees, clears gas-prices (since you can not do both)

---

Flow

• Set junod config gas 1000000 into config.toml
• Run junod tx bank send key juno1... 100ujuno
• Program check config, and sets JUNOD_GAS=1000000 for that run
• User then runs export JUNOD_GAS=500000 in the terminal
• Run junod tx bank send key juno1... 100ujuno
• Program sees gas is 500k, and uses that for this run. Ignoring config. (then to use config again, set JUNOD_GAS="")

UGH the linter changed overnight... 95% of the issues are in the oracle and price feeder - which are being removed anyway

K, you have a PR to take out the price feeder, yes?

PS: this looks like solid usability improvements

@faddat yes, that PR which was just merged to main did this. So I'll pull main in later today & will fix these PRs CI

Cherry picked the lint commits from another branch, this should be good to go now, linter-wise.
