Mnqueues

GCPMonitor receives a `name` parameter when instantiated. This name is now added to the measure that is being sent to GCP.

The measures are:

- mnqueues.{self.name}.number_queue_get
- mnqueues.{self.name}.number_queue_put
- mnqueues.{self.name}.time_in_queue_distribution

1. Add support for time-in-queue measure,
2. improve code quality,
3. improve build & release process

1. MP queues + monitoring,
2. tests,
3. build & project setup.
