Description

When installing Ambari Metrics on Ubuntu 16, the following error is encountered:

2016-09-07 18:55:25,949 - Package Manager failed to install packages. Error: Execution of '/usr/bin/apt-get q -o Dpkg::Options::=-force-confdef --allow-unauthenticated --assume-yes install 'libsnappy1*'' returned 100. Reading package lists...

This is because of a recent change in how libsnappy1 is being packaged:

AMBARI-18025

Now, instead of shipping as a required library, we're installing libsnappy1 on the system. Ubuntu 16, however, uses the newer libsnappy1v5 library. We should change the metainfo.xml of AMBARI_METRICS to declaure libsnappy1v5*.
