_artifact.py: Store additional metadata on the artifact

This commit enriches the metadata we store on artifacts in the
new detatched low/high diversity metadata files:

  * The SandboxConfig is now stored in the artifact, allowing
    one to perform activities such as launching sandboxes on
    artifacts downloaded via artifact name (without backing
    project data).

  * The environment variables is now stored in the artifact,
    similarly allowing one to shell into a downloaded artifacts
    which are unrelated to a loaded project.

  * The element variables are now stored in the artifact, allowing
    more flexibility in what the core can do with a downloaded
    ArtifactElement

  * The element's strict key

All of these of course can additionally enhance traceability
in the UI with commands such as `bst artifact show`.

Summary of changes:

  * _artifact.py:

    - Store new data in the new proto digests.
    - Added new accessors to extract these new aspects from loaded artifacts.
    - Bump the proto version number for compatibility

  * _artifactcache.py: Adjusted to push and pull the new blobs and digests.

  * element.py:

    - Call Artifact.cache() with new parameters
    - Expect the strict key from Artifact.get_meta_keys()
    - Always specify the strict key when constructing an Artifact
      instance which will later be used to cache the artifact
      (i.e. the self.__artifact Artifact).

  * _versions.py: Bump the global artifact version number, as this breaks
    the artifact format.

  * tests/cachekey: Updated cache key test for new keys.
