[FrameworkBundle] added a way to disable the profiler

Before:

  enabled: true  # the profiler is enabled and data are collected

  enabled: false # the profiler is enabled but data are not collected (data can be collected on demand)

  No way to disable the profiler

After:

  enabled: true  # the profiler is enabled and data are collected
  collect: true

  enabled: true  # the profiler is enabled but data are not collected (data can be collected on demand)
  collect: false

  enabled: false # the profiler is disabled
