[Publisher][Admin Panel] Collection of enhancement ideas

[mxosman]

• (From Matt) Bulk creation of agencies via spreadsheet upload - like for when we wanted to make 100s of law enforcement agency accounts in NC
• (From Michelle) Make the copy-supergency-metric-settings-to-child-agencies warning more prominent and dramatic (PR [Publisher] Admin Panel: Update copy for the copy-superagency-metric-settings checkbox and warning message to add more specificity #1185)
• (From Michelle) Extend the copy-supergency-metric-settings-to-child-agencies to allow for selecting child agencies
• (From Jessica) Extend the copy-supergency-metric-settings-to-child-agencies to allow for selecting a subset of metrics to copy over!
• (From Michelle) Add logout button or mechanism to admin panel
• (From Lili) Make it clear that the roles are clickable when adding a new user to an agency (try changing the dropdown input background to white)
