fuel-plugin-ovs: Simplify debian version strings

Remove all suffixes from OVS debian packages, and simplify the
plugin code handling the fetching of said packages.

While at it, enable:
- local mirror caches, by mounting /etc/hosts in the docker
  builder
- HACK: mismatch between debian source versions and debian binaries

-Subject: [PATCH] install.sh: AArch64: Fix dpkg installation issues
-
-There are 2 minor issues with our Armband version string of
-openvswitch packages shipped for fuel-plugin-ovs:
-
-1. Setting up openvswitch-datapath-dkms (2.5.90~08.08-1+amos1)
-   ... Error! Could not find module source directory.
-
-This happens because our version string has a "+" char in it,
-and the /usr/src path looked for is trimmed at that char,
-hence dkms installation is looking for
-"/usr/src/openvswitch-2.5.90~08.08" directory instead of
-"/usr/src/openvswitch-2.5.90~08.08+amos1".
-
-Temporary fix will be to add the following to install.sh:
-ln -s openvswitch-2.5.90~08.08+amos1/ openvswitch-2.5.90~08.08
-
-2. dpkg -i complains about "breaks" dependencies in debian/control
-when reinstalling OVS 2.5.90.
-
-This happens because of faulty dpkg version comparison algorithm:
-$ dpkg --compare-versions 2.5.90~08.08-1+amos1
-  gt 2.5.90 && echo "This should work!"
-$
-
-The temporary fix will be to add --force-breaks to dpkg invocation.
