feat(rust): add `--config` argument to `node create` command

[adrianbenavides]

It loads a json file containing a list of commands that will be executed after creating a node. To generate this json file, the user can use the global --export, --export-as, and --depends-on arguments on any command, that will copy the command input to the desired file.

How to test

ockam node list --export commands.json
ockam node create blue --config commands.json

Other options to export commands to a json file

# Will generate random name for the command
$ ockam node list --export commands.json

# Set name for command 
$ ockam node list --export commands.json --export-as node-list

# Depend on other command
$ ockam node list --export commands.json --depends-on node-create

Structure of the config file

{
  "node-list": {
    "args": [
      "node",
      "list"
    ],
    "depends_on": null
  }
}
