generate a single debug file for a long duration capture (#10279)
* debug: remove the CLI check for debug_enabled

The API allows collecting profiles even debug_enabled=false as long as
ACLs are enabled. Remove this check from the CLI so that users do not
need to set debug_enabled=true for no reason.

Also:
- fix the API client to return errors on non-200 status codes for debug
  endpoints
- improve the failure messages when pprof data can not be collected

* remove parallel test runs

parallel runs create a race condition that fail the debug tests

* snapshot the timestamp at the beginning of the capture

- timestamp used to create the capture sub folder is snapshot only at the beginning of the capture and reused for subsequent captures
- capture append to the file if it already exist

* Revert "snapshot the timestamp at the beginning of the capture"

This reverts commit c2d03346

* Refactor captureDynamic to extract capture logic for each item in a different func

* snapshot the timestamp at the beginning of the capture

- timestamp used to create the capture sub folder is snapshot only at the beginning of the capture and reused for subsequent captures

* Revert "snapshot the timestamp at the beginning of the capture"

This reverts commit c2d03346

* Refactor captureDynamic to extract capture logic for each item in a different func

* extract wait group outside the go routine to avoid a race condition

* capture pprof in a separate go routine

* perform a single capture for pprof data for the whole duration

* add missing vendor dependency

* add a change log and fix documentation to reflect the change

* create function for timestamp dir creation and simplify error handling

* use error groups and ticker to simplify interval capture loop

* Logs, profile and traces are captured for the full duration. Metrics, Heap and Go routines are captured every interval

* refactor Logs capture routine and add log capture specific test

* improve error reporting when log test fail

* change test duration to 1s

* make time parsing in log line more robust

* refactor log time format in a const

* test on log line empty the earliest possible and return

* more specific changelog

* update documentation to reflect current implementation

* add test for behavior when invalid param is passed to the command

* fix argument line in test

* a more detailed description of the new behaviour

* print success right after the capture is done

* remove an unnecessary error check
