fix configuration of strip CPE (needed for confDB)

add a cfi file for handing the definition of the StripCPEESProduce only once
and update coherently the already existing cfi files
I think you need a real PSet, a simple string "parameters" is not allowed as contents of a PSet,
it must be variable=value type expressions.
Perhaps use:
```
parameters = cms.Pset ()
```
and fill the PSet later...
