updating prometheus_client ?

[finkr]

Currently, the exporter require prometheus-client==0.0.19.

More recent version of the library provides some features that would be interesting.

As far as monitoring the exporter (for #128 ), the version 0.4.0 would be good enough.

version 0.7.0 supports Python 3.7 (used in our Dockerfile)

What do you think about it ?
