REVIEW: [NX-529] Add OCompression impl to encrypt records

https://issues.sonatype.org/browse/NX-529
http://bamboo.s/browse/NX-OSSF212-1 :white_check_mark: 

Note: export will decrypt the record content (tested manually using the support zip feature)
very minor but perhaps we should be debug logging the compression name -> instance we are registering?
