Dieter Plaetinck	cda025b5b5	TSDB: demistify SeriesRefs and ChunkRefs (#9536) ... * TSDB: demistify seriesRefs and ChunkRefs The TSDB package contains many types of series and chunk references, all shrouded in uint types. Often the same uint value may actually mean one of different types, in non-obvious ways. This PR aims to clarify the code and help navigating to relevant docs, usage, etc much quicker. Concretely: * Use appropriately named types and document their semantics and relations. * Make multiplexing and demuxing of types explicit (on the boundaries between concrete implementations and generic interfaces). * Casting between different types should be free. None of the changes should have any impact on how the code runs.

Robert Fratto	bc72a718c4	Initial draft of prometheus-agent (#8785) ... * Initial draft of prometheus-agent This commit introduces a new binary, prometheus-agent, based on the Grafana Agent code. It runs a WAL-only version of prometheus without the TSDB, alerting, or rule evaluations. It is intended to be used to remote_write to Prometheus or another remote_write receiver. By default, prometheus-agent will listen on port 9095 to not collide with the prometheus default of 9090. Truncation of the WAL cooperates on a best-effort case with Remote Write. Every time the WAL is truncated, the minimum timestamp of data to truncate is determined by the lowest sent timestamp of all samples across all remote_write endpoints. This gives loose guarantees that data from the WAL will not try to be removed until the maximum sample lifetime passes or remote_write starts functionining.
