Feature/add grooming parameters for fastjet

this is a backport to 71X for git PR 4705. It adds needed grooming parameters to an hlt cfi.py file and modifies the fastjetjetproducer module to read in values of the parameters as opposed to just checking for their existence.


Hi,

Likewise here:

You added two parameters as cms.int(). This type does not exist.
You need to add it as cms.int32(.).
Please submit a new backport PR to correct this.
You can check for such errors by running
```
python hltak5CaloJets_cfi.py
```
