Checksum parameter cfi export (75X)

[smorovic]

CRC32 is checked by default, however parameter to control this is not exported.

We need a way to switch this off in heavy ion test setup, so two changes are provided:

• export of the parameter (for the new template)
• reuse adler32 setting as default (as we replaced adler32 with crc32c, for existing templates).

Also, two other not previously exported parameters were added to cfi files, and input source parameter defaults were changed to defaults used in production.

Backport of #11535

For #11536 6a5ad2f

For Heavy Ions, exporting checksum parameter so it can be toggled as necessary. There should be no change in monitored quantities. #11535 is the 76X version of this PR, and it has already been approved by Reco.

The code changes are satisfactory, and Jenkins tests against baseline CMSSW_7_5_X_2015-09-27-2300 show no significant differences, as expected.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_5_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_7_6_X is complete. This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar
