 - `list` - lists the keys in the Gossamer keystore
 - `import` - imports a key from a keystore file
 - `import-raw` - imports a raw key from a keystore file

 - `keystore-path` - path to the Gossamer keystore
 - `keystore-file` - path to the keystore file
 - `chain` - path to the human-readable chain-spec file
