[xdebug-general] feature request - dump traces file to disk only if total script execution time is greater or equals a threshold in seconds

Hello,

I'd like to suggest a feature that might be useful when doing load/stress
testing.

Normally, if one is not satisfied with load/stress testing results and
wants to investigate root causes, only requests that took longer than X
seconds to execute matter.
However, right now such testing will generate tons of profiler traces
files, so additional manual files cleaning/filtering has to be done.

It would be great to have a configuration parameter like the following:

xdebug.profiler_request_time_threshold
Type: integer, Default value: 0
When this setting is set to a value greater than 0, trace files will be
dumped to disk only if total request processing time is greater or equals
the threshold (in seconds).
