Iteration 0.5: Update existing export functions to include custom role

Release notes

Problem to solve

Self-managed User Permission Export and group member report return only default roles. This should also return custom roles.

Proposal

Self-Managed Instance Report

Update the existing self-managed export to include the following:

• Access level currently returns default roles. This column should also include the custom role name too.

Group Member Report

Update group members export to include the following:

• Max role column currently returns default roles. This column should include the custom role name too.
