After deep investigating, i found that Prometheus labels could not contain special characters.
metric-names-and-labels
So, the problem is with Prometheus client library.
I had the idea to replace special chars with the allowed underscore

.but, i could not retrieve buckets after registration to the client, that´s why i store the origin labels in the cache.
Fixes #34
Will Fixes #29 as well
