Feat(CLI): Infra manifest support default modules

[cbrzn]

This PR aims to add the capability to add a default module in the manifest, this means that we can do:

format: 0.0.1-prealpha.2
modules:
  eth-ens-ipfs: default
  mainnet-fork:
    path: ./mainnet-fork

And it will load both modules

edit: When developing this feature, I noticed that it was not possible to declare a file (i.e: my_folder/docker.compose.yaml) as a value for path in local modules, I found this weird, so I went ahead and add support to add files or folder, this way is more friendly to interact with infra :-D

so basically now this is supported:

format: 0.0.1-prealpha.2
modules:
  eth-ens-ipfs: default
  mainnet-fork:
    path: ./mainnet-fork/docker-compose.yaml
  ropsten-fork:
    path: ./ropsten-fork
