So here is how we can rectify the bigger name

1. Rename the class ConnectionEntry.java to ColleagueConnection.java, as this is wrong on both fronts naming and consistency
2. Rename api getColleaguesConnectionEntries() to getColleagueConnections()
3. Rename api getCommonColleaguesProfiles() to getCommonColleagues()
4. Rename api getCommonColleaguesConnectionEntries() to getCommonColleagueConnections()

Use this consistency everywhere, lets not Entries or Entry in api names which makes the api name longer without adding more meaning to it
