    Description

      We introduced a GDB command in SERVER-45556 to dump all active RecoveryUnits. This is useful when diagnosing from the MDB perspective and we use this in our hang analysis tools to debug test timeouts in our CI system.

      To supplement this information, It would be useful to have diagnostic output from the WiredTiger point of view, specifically debug information provided by the WT_CONNECTION::debug_info() function introduced in WT-3529.

      A similar request was previously made in SERVER-52956.

      Note: this ticket also added an "includeStorageEngineDump" option to the "lockInfo" command to print the WT debug_info to the logs.
