Introduce TSDB changes for appending metadata to the WAL (#10972)
* Append metadata to the WAL Signed-off-by: Paschalis Tsilias <paschalist0@gmail.com> * Remove extra whitespace; Reword some docstrings and comments Signed-off-by: Paschalis Tsilias <paschalist0@gmail.com> * Use RLock() for hasNewMetadata check Signed-off-by: Paschalis Tsilias <paschalist0@gmail.com> * Use single byte for metric type in RefMetadata Signed-off-by: Paschalis Tsilias <paschalist0@gmail.com> * Update proposed WAL format for single-byte type metadata Signed-off-by: Paschalis Tsilias <paschalist0@gmail.com> * Implementa MetadataAppender interface for the Agent Signed-off-by: Paschalis Tsilias <paschalist0@gmail.com> * Address first round of review comments Signed-off-by: Paschalis Tsilias <paschalist0@gmail.com> * Amend description of metadata in wal.md Signed-off-by: Paschalis Tsilias <paschalist0@gmail.com> * Correct key used to retrieve metadata from cache When we're setting metadata entries in the scrapeCace, we're using the p.Help(), p.Unit(), p.Type() helpers, which retrieve the series name and use it as the cache key. When checking for cache entries though, we used p.Series() as the key, which included the metric name _with_ its labels. That meant that we were never actually hitting the cache. We're fixing this by utiling the __name__ internal label for correctly getting the cache entries after they've been set by setHelp(), setType() or setUnit().
