Provide mechanism for junctioned plugins to express their dependencies #1894

As discussed in https://gitlab.com/BuildStream/bst-plugins-experimental/-/issues/59, junctioned plugins currently cannot express which packages they need let alone which versions of said packages they need. BuildStream and plugins should agree upon API/metadata for providing this information so BuildStream can gracefully error out when plugin dependencies are unsatisfied.

@gtristan @jjardon this is not limited to just package requirements. Plugin junctions also cannot state which version of Python they need. There is no metadata for this.
