vm_tools: Add feature flags for termina

When we make changes to packages inside Termina they don't take affect
until we uprev Termina (currently happens weekly'ish) and beyond
compilation and unit tests, changes aren't tested by the CQ until we
have a pin uprev CL (again, weekly'ish). This means that if something is
broken we don't find out for a week, then whoever's performing the uprev
has to look through a week's worth of changes, try and figure out which
is to blame, revert it, then start again from the beginning. This costs
us O(days) of calendar time per attempt.

With these CLs we now have feature flags. Land your change to
Tremplin/maitre'd/whatever behind a flag, wait for the uprev, then
enable the flag. Now enabling the feature happens with a host CL so it
gets tested individually on the CQ.

BUG=none
TEST=Manual, add a flag and check it's piped all the way through
maitre'd and tremplin
