HLT updates on top of what is in CMSSW742

[perrotta]

This PR includes #8916, and further updates the development HLT menus and local tests for them.
It may be considered a backport in 74X of #9148 + #9161

The _v1 frozen menus (used in RelVals and in the MC production) are not touched
_v2 of those frozen menus are added

Will we ever get to a point where HLT updates don't come with 400K source code line-changes

@slava77 : unlikely, al least until we need to add new paths in the menu and modify the existing ones
:-)
