[PATCH 0/6] add per-iteration perf_test tweaks

[Jan Tluka]

This patchset modifies the current implementation of the performance test
tweaks.

Before the patch set the user was unable to add performance test tweaks
on per iteration basis. It was only possible to add/remove tweaks
before/after the whole set of the performance test measurement iterations.

The patchset adds BasePerfTestIterationTweakMixin to RecipeCommon.Perf.Recipe
that provides a common API for that. The actual tasks to be performed
before/after each iteration needs to be defined by a specific mixin
class.

In the same manner the already existing BasePerfTestTweakMixin has been
moved to RecipeCommon.Perf.Recipe to have both APIs at the same place.

Jan Tluka (6):
  RecipeCommon.Perf.PerfTestMixins: add BasePerfTestIterationTweakMixin
  RecipeCommon.Perf.Recipe: add per-iteration tweaks using
    BasePerfTestIterationTweakMixin
  lnst.Recipes.ENRT.PerfTestMixins: move BasePerfTestTweakMixin to
    RecipeCommon
  RecipeCommon.Perf.PerfTestMixins.BasePerfTestTweakMixin: move
    get_flow_measurements_from_config to standalone function
  lnst.Recipes.ENRT.PerfTestMixins: add DropCachesPerfTestMixin
  Recipes.ENRT.PerfTestMixins: extend CommonPerfTestTweakMixin with
    DropCachesMixin
