[ACLs] Allow survey organizers to control visibility of job data

[gino-m]

My interpretation of feature requested by @lecrabe:

• Survey organizers should be able to specify whether data collectors can see each others' data (LOIs, submissions).
• Survey organizers will always see all data.

We should be sure to enforce this through Firestore rules.

@lecrabe Please cmiiw. @vittorino for UXD, @amegantz for UXW.

@gino-m Is this part of the ACL work for 3/5 field testing or is this different? If not part of field testing we should punt from this milestone

This is different. Not needed for field testing, but def. needed for IDF announcement.

Tasks:

• add toggle in web interface on sharing screen
• add Firebase rules to enforce visibility
• Apply toggle on web & android
  May need additional issues to track the multiple tasks (I'll look into this)
