Release v0.57.2

Note: we skipped v0.57.0 and v0.57.1 in order to have the same version number as core.

The OpenTelemetry Collector Contrib contains everything in the opentelemetry-collector release (be sure to check the release notes there as well!)"

🚀 New components 🚀

• chronyreceiver: This will add in support for measuring tracking data from chronyd (#11789)

💡 Enhancements 💡

• datadogexporter: Add host metadata tags to metrics on serverless environments (#12486)

• observer: Add observer.Endpoint.ID to Env() (#12751)

• aerospikereceiver: Scrape nodes in parallel when in collect_cluster_metrics mode. (#11563)

• coralogixexporter: Add logs client to coralogixexporter (#12601)

• awscontainerinsightreceiver: Pod Detection changes to support Containerd runtime in K8s (#12638)

• dockerstatsreceiver: Enable a featuregate for the new implementation of scrape. Change the units in the new implementation to align to semantic convention. (#9794)
  This allows the new implementation of scrape to be used via a featuregate.
  It also updates the tests, which now test for expected descriptions and units in the new implementation.

• healthcheckextension: Use confighttp.HTTPServerSettings to allow tls and auth. (#12668)

• demo: Add connection time out for client in examples/demo/client (#12431)

• prometheusexporter: Export target_info metrics with the resource attributes. (#8265)

• resourcedetectionprocessor: update Azure resource detector to save "name" from Azure metadata API in azure.vm.name attribute (#12779)

• pkg/telemetryquerylanguage: Adds standard contexts to the module that should be used when interacting with OTLP traces, metrics, and logs. (#12589)

• pkg/telemetryquerylanguage: Adds a set of otel functions to the telemetryquerylanguage module. (#12754)

• pkg/telemetryquerylanguage: Adds a set of common functions to the telemetryquerylanguage module. (#12739)

• cumulativetodeltaprocessor: Cumulative Histogram metrics will now be converted to delta temporality and are no longer skipped. (#12423)
  This means that consumers who currently rely on Histograms being skipped would need to ensure they are excluded via config.

• dockerstatsreceiver: Initial PR for onboarding dockerstats onto mdatagen scraping. (#9794)
  Additionally appends the internal docker client to allow options (bug fix).

• mongodbreceiver: Enhance mongodbreceiver by adding new metrics (#12672)

• chronyreceiver: Added internal chrony client (#11789)
  -| Added an internal client for the receiver with modifications of the upstream client to fit the collector

• receivercreator: add per-receiver resource_attribute and validate endpoint type keys on global (#11766)

• pkg/translator/signalfx: Optimize ToMetrics to emit datapoints under the same metric when same name and type. (#12902)

• sqlqueryreceiver: Add static_attributes optional configuration to allow adding attributes/tags to queried metrics. (#11868)
