[fuel-plugins] Ubuntu repos ignore repeating packages

[Alexandru Avadanii]

Some plugins may have repeating packages, which are filtered by dpkg-scanpackages.

Steps to reproduce (ODL example):
1. Build ODL plugin for multiarch (amd64 + arm64), which includes arch-specific DEBs (see [1])
2. Analyze plugin repo's Packages.gz contents

Expected results:
All packages built and shipped with ODL plugin should be listed in Packages.gz (see [2]).

Actual results:
Only one of the arch-specific DEBs will be listed (see [3]).

Description of the environment:
 Operation system: Ubuntu Trusty 14.04 (arm64)
 Versions of components: stable/mitaka
 Related projects installed: Fuel@OPNFV + Armband patches to build ODL for multiarch [4]

Proposed changes:
Add "-m, --multiversion (allow multiple versions of a single package)" flag to dpkg-scanpackages call.

    Support multi versions of package in fuel plugin

    Some plugins may have repeating packages, which are currently filtered
    by dpkg-scanpackages. This is the case for multiarch builds of some Fuel
    plugins like ODL, which build and ship both amd64 and arm64 DEBs for ODL
    prereqs. Allow multiple versions of a single package, by passing the
    `-m` flag to dpkg-scanpackages when building local Ubuntu repo.
