feat(otel): Metrics_callbacks module 
this module allows the user's programs and libraries to register
some callbacks that will be regularly called to produce metrics.

fix: proper starting point for cumulative metrics 
use the start of the program as a fixed reference point.

feat: use a ref for Globals.global_attributes 
sometimes it's useful to be able to modify them from the code itself.
For example a client or service might generate a unique Uuidm for its whole
lifetime, and add that as an attribute to later filter on it.

fix: yet another fix for emitting GC metrics 
now, the frontend (Opentelemetry) is responsible for signalling the
backend when to emit GC stats; but the backend just samples GC metrics
on the next `tick()` and pushes them in the next batch. This saves us
from having to worry about re-entrancy and GC metrics being emitted
during the emission of something else.

feat(collector): move GC metrics logic to the collector 
this helps avoiding reentrancy issue, where the collector allocates,
triggers the GC metrics alarm, which tries to push new metrics in the
middle of a batch (currently leading to a potential deadlock).
