* minor fix
* Add support for unauthenticated pprof access on a per-listener basis, as we do for metrics.
* Add missing pprof sub-targets like 'allocs' and 'block'. Capture the goroutine subtarget a second time in text form. This is mostly a convenience, but also I think the pprof format might be a bit lossy?
* cli: initial work on debug; server-status target
* debug: add metrics capture target (#7376)
* check against DR secondary
* debug: add compression
* refactor check into preflight func
* debug: set short test time on tests, fix exit code bug
* debug: use temp dir for output on tests
* debug: use mholt/archiver for compression
* first pass on adding pprof
* use logger for output
* refactor polling target capture logic
* debug: poll and collect replication status
* debug: poll and collect host-info; rename output files and collection refactor
* fix comments
* add archive test; fix bugs found
* rename flag name to singular target
* add target output test; scaffold other tests cases
* debug/test: add pprof and index file tests
* debug/test: add min timing check tests
* debug: fix index gen race and collection goroutine race
* debug: extend archive tests, handle race between program exit and polling goroutines
* update docstring
* debug: correctly add to pollingWg
* debug: add config target support
* debug: don't wait on interrupt shutdown; add file exists unit tests
* move pprof bits into its goroutine
* debug: skip empty metrics and some pprof file creation if permission denied, add matching unit test
* address comments and feedback
* Vault debug using run.Group (#7658)
* debug: switch to use oklog/run.Group
* debug: use context to cancel requests and interrupt rungroups.
* debug: trigger the first interval properly
* debug: metrics collection should use metrics interval
* debug: add missing continue on metrics error
* debug: remove the use of buffered chan to trigger first interval
* debug: don't shadow BaseCommand's client, properly block on interval capture failures
* debug: actually use c.cachedClient everywhere
* go mod vendor
* debug: run all pprof in goroutines; bump pprof timings in tests to reduce flakiness
* debug: update help text
