🧰 Bug fixes 🧰

• cmd/chloggen: Compare changelog to common ancestor with main (#12149)
• logstransformprocessor: Remove support for storage (#12424)
• elasticsearchreceiver: Remove unused disk_usage_state attribute from documentation (#12429)
• filterlog: change OR to AND logic for filtering logs - as desribed, and as is done for span filtering (#11439)
• lokiexporter: Wrap quotes around log message (#11827)
• tooling: Fix a bug in the makefile causing make rpm-package to fail (#12162)
• prometheusexporter: Fix cumulative condition for the delta-to-cumulative (#4153)
• xrayreceiver: Ensure that the UDP Poller ends the obsreport span it creates with every loop. (#12299)
  This avoids a memory leak that can happen when spans are created to track received
  segments but never ended.
• googlecloudexporter: Various bug fixes in parsing OTel logs to GCP LogEntries (#12157)
• datadogexporter: Fix logs related to the source provider. (#12160)
• pkg/stanza/fileconsumer: Fix issue where reader could become stuck on newlines (#10125, #10127, #10128)
• receivercreator: dynamically created receivers log with their name field (#16481)
• skywalkingreceiver: Fix skywalking traceid and spanid convertion (#11562)
• spanmetricsprocessor: Fixes the number of explicit bucket counts by removing the manually added "catch-all" bucket. (#11784)
• spanmetricsprocessor: Fix concurrency bug causing premature key eviction. (#9018)
• spanmetricsprocessor: Removes a comment that is no longer relevant due to a fix. (#12427)
• sqlqueryreceiver: Metrics did not contain a timestamp. Timestamps are required for a variety of backends, especially prometheus. In order to work with prometheus we must set the metrics timestamp because metrics with the default timestamp (year 1970) will be dropped by prometheus backends. (#12088)
• statsdreceiver: Fixing parsing issue for values on statsd receiver (#12120)
• vcenterreceiver: Fixes calculation of vcenter.vm.disk.utilization. (#12342)
