invalid/unhandled type stored in mongo meters

[Igor Degtiarov]

In upstream we have a bug https://bugs.launchpad.net/ceilometer/+bug/1474031 that also affected fuel.

In some cases MongoDB and HBase return integer values from samples and statistics, but wsme expected a float type.

So we need to cast Int types to float after data is taken from database.

The commit to be reverted by https://review.fuel-infra.org/#/c/10343/ . The plan is to fix regression in upstream and commit two fixes again.

Described in the original bug behavior is looked only in MongoDB 3.+. Agree the fact what MOS Ceilometer 7.0 installs MongoDB 2.6.9 this bug doesn't affect MOS 7.0.
It also correct for external MongoDB, because installed pymongo version (2.7.2) isn't compatible with MongoDB 3+ and we can't use higher than 2.6.9 db version in this case.

So, I suggest to move this bug into "Invalid" state.
