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 Change-Id: Id5c3cdc90700563aff881e5831285a1330a2c034 Partly-Implements: blueprint api-request-stats
