Currently Prometheus will always request gzip compression from the target when sending scrape requests.
HTTP compression does reduce the amount of bytes sent over the wire and so is often desirable.
The downside of compression is that it requires extra resources - cpu & memory.
This also affects the resource usage on the target since it has to compress the response
before sending it to Prometheus.
This change adds a new option to the scrape job configuration block: enable_compression.
The default is true so it remains the same as current Prometheus behaviour.
Setting this option to false allows users to disable compression between Prometheus
and the scraped target, which will require more bandwidth but it lowers the resource
usage of both Prometheus and the target.
Fixes#12319.

* Added ability to specify scrape protocols to accept during HTTP content type negotiation.
This is done via new option in GlobalConfig and ScrapeConfig: "scrape_protocol"

* Followup on OpenTelemetry migration
- tracing_config: Change with_insecure to insecure, default to false.
- tracing_config: Call SetDirectory to make TLS certificates relative to the Prometheus
configuration
- documentation: Change bool to boolean in the configuration
- documentation: document type float
- tracing: Always restart the tracing manager when TLS config is set to
reload certificates
- tracing: Always set TLS config, which could be used e.g. in case of
potential redirects.

* Allow escaping a dollar sign when expanding external labels
There is currently no mechanism to natively escape a dollar sign
in the os.Expand function. As a workaround, this commit modifies
the external label expansion logic to treat a double dollar ($$)
as a mechanism for escaping the dollar character.

This creates a new `model` directory and moves all data-model related
packages over there:
exemplar labels relabel rulefmt textparse timestamp value
All the others are more or less utilities and have been moved to `util`:
