Add a new debug endpoint that returns a text-formatted representation of all the stack traces that performed a retrieval of a separated value while the profile was being collected. This provides better observability into what code paths are suffering more expensive value retrievals. Epic: none Informs: cockroachdb#146575 Release note: none

157784: tree: speed up two tests r=yuzefovich a=yuzefovich We just saw a package-level test timeout of 1 minute being hit because `TestRandomInjectHints` took 29s and `TestParseArrayRandomParseArray` took 16s before interruption. This commit reduces the number of iterations by 5x and 10x, respectively. Fixes: #157256. Release note: None 157852: mixedversion: remove special case for skipping current version r=williamchoe3 a=DarrylWong In the past, we used to bump CRDB's minSupportedVersion _before_ bumping CRDB's current version. Consider the old version bump process: 1. Bump minimum supported version (e.g. 25.2→25.3) 2. Bump current version (e.g. 25.4→26.1) 3. Bump minimum supported version again (e.g. 25.3→25.4) After the first step, we would be in a state where the mixed version framework would see v25.3 as a skippable version (.1 and .3 ordinal versions are skippable), but since the minimum supported version is 25.3, 25.2→25.4 is (temporarily) not a legal upgrade. This required a special case to disallow skip upgrades in the case of this edge case. However, we now bump the current version _first_. This means we no longer need to protect against the above and we actually hit a different bug. Since we now bump the current version first, the special case will always view the current version as having multiple supported predecessors and force a skip upgrade even if not applicable. Release note: none Epic: none 157919: roachprod: fix service registry unit test name collision r=golgeek a=DarrylWong We were previously generating cluster names with Uint32, which is not sufficient enough to prevent naming collisions after 1000 iterations. Instead, use a RandString of length 10.
