build: Rework patch mechanism for Fuel submodules

While refactoring the patching mechanism, take care of:
- Sync submodule handling with Fuel@OPFNV;
- build: Investigate/prepare for moving patches to Fuel@OPNFV;
- build: Investigate divergent fuel-mirror;
- ISO build: cacheid for Fuel comps should not depend on
  Armband git commit;

CHANGE:
 Rename/shuffle patches while grouping them in "features",
 preparing for upstreaming them to Fuel@OPNFV and beyond.

CHANGE:
 Allow linking patches for better representing the dependency
 between one patch and different features.
 e.g. 0001-Add-arch-to-nailgun-release-and-target-image.patch:
   - part of `multiarch-fuel`, because it extends Fuel;
   - part of `direct-kernel-boot`, as arch is required for that;
   - part of `cross-bootstrap`, target image is arch-dependent;
 NOTE: Patch links are not staged to Fuel@OPNFV, they only serve
 as markers that a specific patch is part of a feature.

CHANGE:
 Kill all Fuel component submodules, now handled in Fuel@OPNFV:
  - fuel-agent
  - fuel-astute
  - fuel-library
  - fuel-mirror
  - fuel-nailgun-agent
  - fuel-web

CHANGE:
 Move armband-fuel-config.mk to armband git root.

FIXME: m1.micro-Increase-profile-RAM-size-to-128MB.patch is NOT
 part of `cross-bootstrap` feature, but patch context says so ...

FIXME: 0001-Add-arm64-deb-repositories-setup.patch is broken at
 `make patches-export` by removing spaces at EOL.

v2 -> v3:
 * Phony patch support (links to show a patch belongs to a feature);
 * Updated README.md
v3 -> v7:
 * Re-export Fuel submodules & plugins patches (update patch context);
 * Update Cavium mail addresses (s/caviumnetworks.com/cavium.com/);
 * Ignore submodule changes;
 * Add armband git repo info to gitinfo_fuel.txt at build time;

+
+For now the arch is hardcoded for simplicity. We should detect this
+but how? If we're multi-arch then one bootstrap image should be built

+Subject: [PATCH] post-scripts: Enable systemd-binfmt for first boot.
+
+IMPORTANT:
+This commit introduces the following file on Fuel Master,
+containing the list of arch supported for target nodes:
+</etc/fuel_openstack_arch>.
+
+This file is created AFTER pre.d OPNFV scripts are ran, also by
+bootstrap_admin_node.sh, BEFORE the post.d scripts are executed.
+NOTE: Arch format is the same used by dpkg (e.g.: "amd64 arm64")
+
+Based on the number of foreign architectures we should support
+(the list of archs in /etc/fuel_openstack_arch minus native arch),
+we determine whether cross-builds are expected, in which case
+binfmt support should be functional during first Fuel Master boot.
+
+Since systemd-binfmt service has a series of preconditions for
+starting, which are tested early during first boot, some of them
+are NOT YET true (e.g. no binfmt handlers are present before
+qemu-user-static package is installed), so the service is not
+automatically started. Of course, this only affects the first boot.
+
+Finally, this commit adds an OPNFV post-install script in
+/opt/opnfv/bootstrap/post.d, which starts systemd-binfmt service.

+Subject: [PATCH] mcagent: Increase max shell command timeout to 2h
+
+Since `execute_shell_command` mcagent is used for building the target
+image and the timeout provided in the astute task is just respected on
+the Astute level (on mcollective level this timeout is actually a
+minumum between value provided and ddl value) we need to increase it
+for Armband operation.
+
+Because Armband builds the target image via `qemu-debootstrap`, it can

+Currently we're close to 40 minutes of image building (thanks to
+qemu-debootstrap). If network connectivity is a bit slow (happened to
+me) it's easy to go over 1h limit. Therefore let's push this to 2 hours
