v2.6.0: Fix PCS/TRS resource leaks and scaling issues

[2.6.0] - 2024-11-25

Changed

• Updated hms-trs-app-api vendor code (bug fixes and enhancements)
• Passed PCS's log level through to TRS to match PCS's
• Configured TRS to use connection pools for status requests to BMCs
• Renamed PCS_STATUS_HTTP_TIMEOUT to PCS_STATUS_TIMEOUT as it is not an http timeout
• Added PCS_MAX_IDLE_CONNS and PCS_MAX_IDLE_CONNS_PER_HOST env variables which allow overriding PCS's connection pool settings in TRS
• Added PCS_BASE_TRS_TASK_TIMEOUT env variable which allows the timeout for power transitions and capping to be configured
• The above variables are configurable on PCS's helm chart
• At PCS start time, log all env variables that were set
• Added PodName global to facilitate easier debug of log messages
• Log start and end of large batched requests to BMCs
• Fixed many resource leaks associated with making http requests and using TRS
• Update required version of Go to 1.23 to avoid golang/go#59017
