feat: created config base env file

[Zfinix]

Closes #238

This looks good for a small config, but would it scale? For example, one of the things we'll add is fee configuration (see Keplr for example). It might look something like this:

fees:
  - denom: uosmo
    amount:
      low: 1000
      normal: 3000
      fast: 4000
  - denom: uion
    amount:
      low: 10
      normal: 20
      fast: 40

Here's the amount of configuration Keplr requires:

I believe it would scale, the problem here is that we don't want to build a parser for that structure and we want to be able to still use --dart-define and also change the env variables using hotreload and hot restart, this is only possible if we write it in dart

@andrzejchm i also added updates to the docs

[andrzejchm]

awesome job @Zfinix ! Its much cleaner now. one comment and we're good to merge

[andrzejchm]

• 10.0.2.2 - localhost for android emulators
• lhttp://localhost - ios simulator

you'll have to stick with only 1 version, I suggest going with http://localhost for both LCD and grpc
