Georgy Okrokvertskhov f84e8450da Add per API call statistics
This patch adds a new decorator which calls a stats
collection code to collect usage information per tenant

StatisticsCollection class is added a a stats storage.

Add hostname to stats

As Murano has multi-service deployment it is
necessary to add hostname to each stats
in order to understand which API service
provides them.

Add DB model for stats

This patch adds a new DB model to keep API stats in the DB.
As it is possible to have multiple Murano API servers
we will keep stats for each Murano API instance

Fix stats update to save data to DB

Fixed issues with column names
Added logic to calculate request\sec
and errors\sec based on previous values
