trivial: Remove files from 'tools'

Two files are removed.

'ebtables.workaround' was required for libvirt < 1.2.11 for the reasons
described in the file itself. We no longer support this version of
libvirt, thus, the workaround can be removed.

'regression_tester' is a tool for running tests in a patch against old
code, to ensure the tests validate what the patch is supposed to be
fixing. This is unmaintained and is not referenced anywhere, and should
therefore be removed as it's likely bitrotted (or will do so).

-# This is a terrible, terrible, truly terrible work around for
-# environments that have libvirt < 1.2.11. ebtables requires that you
-# specifically tell it you would like to not race and get punched in
-# the face when 2 run at the same time with a --concurrent flag.
-#
-# INSTALL instructions
-#
-# * Copy /sbin/ebtables to /sbin/ebtables.real
-# * Copy the ebtables.workaround script to /sbin/ebtables
-#
-# Note: upgrades to ebtables will overwrite this work around. If you
-# are packaging this file consider putting a trigger in place so that
-# the workaround is replaced after ebtables upgrade.
-#
-# Additional Note: this file can be removed from nova once our libvirt
-# minimum is >= 1.2.11.

-"""Tool for checking if patch contains a regression test.
-
-By default runs against current patch but can be set to use any gerrit review
-as specified by change number (uses 'git review -d').
-
-Idea: take tests from patch to check, and run against code from previous patch.
-If new tests pass, then no regression test, if new tests fails against old code
-then either
-* new tests depend on new code and cannot confirm regression test is valid
-  (false positive)
-* new tests detects the bug being fixed (detect valid regression test)
-Due to the risk of false positives, the results from this need some human
-interpretation.
