Antonio Ojea 3f3e1d507d add new metrics for the internal client-go transport generator ...

Add two new metrics to monitor the client-go logic that
generate http.Transports for the clients.

- rest_client_transport_cache_entries is a gauge metrics
with the number of existin entries in the internal cache

- rest_client_transport_create_calls_total is a counter
that increments each time a new transport is created, storing
the result of the operation needed to generate it: hit, miss
