Adjust cache-chroniclemap to new metric sanitization scheme

Gerrit's I6a5366fa0f1f change improved metrics name sanitization to
avoid collisions.

Introduce CacheNameSanitizer to:
* keep the backward compatibitlity with the oridinary cache names e.g.
  `diff_summary` stays `diff_summary`
* all the other cases are sanitized according to metrics sanitization
  rules e.g. `very+confusing.cache#name` becomes

Tests were adjusted to new sanitization rules.
