Extend ethpm release for local manifests

[njgheorghita]

As a user, who has generated a local manifest (i.e. with ethpm create basic-manifest or ethpm create manifest-wizard) I want to be able to easily release the manifest to my registry by simply providing the path to the local manifest

ethpm release --manifest-path /path/to/manifest.json --keyfile-password [PASSWORD]

Command will automatically pin the manifest to ipfs (infura / local /ethpm nodes) & release the manifest with its embedded package name & version to the active registry.

And improve log msgs for better ux.
