feat(cli): Implemented the download config method to the init command
Browse files Browse the repository at this point in the history 
I have tested three scenarios:

1) default config which generates the random chain id
2) betanet config which is generated
3) betanet config which is downloaded and should have tracked shards = [0] and boot_nodes set.

Tested for the test chain command:
```
