Add Group Visibility field in UserGroup Entity of Sharing Service

[Shubham Kumar]

Hi Dev,

For my assignment, my goal is to add the Group Visibility enum type field
where PRIVATE value is 1, PUBLIC value is 2, in UserGroup Entity.
I have to make changes to thrift file. I am not sure how to proceed with
the testing for this. Should I go for local database setup to test Java
client or remote gateway?

Best.
