New module for selecting tracks matched to a muon

[KyeongPil-Lee]

This PR adds a new module to select tracks only matched to a muon in HLT.
In current HLT menu, PF uses the tracks produced in L3 muon reconstruction sequence before applying ID, which could increase the rate of PF-related triggers (e.g. MET triggers).
Instead of feeding the tracks before ID, the output of this module (the "clean" tracks matched to a muon after ID) can be fed to PF modules so that the rate of triggers using PF can be stable.
Backport to 10_1_X is also needed.

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)

[fabiocos]

@Martin-Grunewald this new module is not run in basic tests here, I assume it was tested offline by the HLT group, am I correct?

[Martin-Grunewald]

@fabiocos
Indeed, the author reported that no problem was found in quick tests (No crashes, # passing events for a MET trigger reduced).
