CIF-1027 - Clean up occurrences of ccif in commerce-cif-connector project

[LSantha]

There are several occurrences of the old acronym CCIF in commerce-cif-connector as "ccif" in component names and variable names which is now obsolete and misleading and it should be replaced with cif.

Description

I've replaced occurrences of ccif with cif.
