Adds use of CustomCollector in Prometheus exporter

Using a CustomCollector gives more control over the collection
process, which allows handling the removal of metrics when a NS
is deleted. Metrics now have a lifespan of a collection cycle, so
metrics of deleted vdus are now not visible in the exporter.

It also adds MonCollector class, which allows to abstract collection
logic and facilitates testing.
