Subject: [PATCH] CI: deploy-cache: Store and reuse deploy artifacts

Add support for caching deploy artifacts, like bootstraps and
target images, which take a lot of time at each deploy to be built,
considering it requires a cross-debootstrap via qemu-user-static and
binfmt.

For OPNFV CI, the cache will piggy back on the <iso_mount> mechanism,
and be located at:
/iso_mount/opnfv_ci/<branch>/deploy-cache

TODO: Use dea interface adapter in target images fingerprinting.
TODO: remote fingerprinting
TODO: differentiate between bootstraps and targetimages, so we don't
end up trying to use one cache artifact type as the other.
TODO: implement sanity checks for bootstrap and target images;
TODO: switch `exec_cmd('mkdir ...')` to `create_dir_if_not_exists`;

JIRA: ARMBAND-172

+Subject: [PATCH] bootstrap_admin_node.sh: deploy_cache install hook
+
+Tooling on the automatic deploy side was updated to support deploy
+caching of artifacts like bootstrap (and id_rsa keypair), target
+images etc.
+
+Add installation hook that calls `fuel-bootstrap import` instead of
+`build` when a bootstrap tar is available in the agreed location,
+/var/lib/opnfv/cache/bootstraps/.

+###############################################################################
+# 1. do_fingerprints
+#    Can be called as soon as a Fuel Master ISO chroot is available.
+#    This will gather all required information for uniquely identifying the
+#    objects in cache (bootstraps, targetimages).
+# 2. inject_cache
+#    Can be called as soon as we have a steady SSH connection to the Fuel
+#    Master node. It will inject cached artifacts over SSH, for later install.
+# 3. (external, async) install cached bootstrap instead of building a new one
+#    /sbin/bootstrap_admin_node.sh will check for cached bootstrap images
+#    (with id_rsa, id_rsa.pub attached) and will install those via
+#    $ fuel-bootstrap import opfnv-bootstraps-cache.tar
+# 4. install_targetimages_for_env
+#    Should be called before cloud deploy is started, to install env-generic
+#    'env_X_...' cached images for the current environment ID.
+#    Static method, to be used on the remote Fuel Master node; does not require
+#    access to the deploy cache, it only moves around some local files.
+# 5. extract_targetimages_from_env
+#    Should be called at env deploy finish, to prepare artifacts for caching.
+#    Static method, same observations as above apply.
+# 6. collect_artifacts
+#    Call last, to collect all artifacts.
