Script to copy/reset available reports (for group and role):

  - duplicate report structure from one group to another group
  - duplicate report structure from group to role, which means to each group having that role
  - remove cutomized report sructure from group
  - remove customized report structure from role, which means from each group having that role
EXAMPLE: bundle exec ruby ./tools/copy_reports_structure -s EvmGroup  -r SomeRole
         bundle exec ruby ./tools/copy_reports_structure -p SomeRole
