Unify service accounts to one kind, add manager field, make homeDirectory/loginShell editable

Removes the LDAP bind-only service account type in favor of a single
Unix/POSIX account model, surfaced in a new Users > Service Accounts tab.
Adds a multi-valued `manager` field to every account (defaults to the
creator, editable, and grants edit rights on the accounts a person manages
without needing app_sso_admin). homeDirectory and loginShell are now
editable from the profile edit form.

Bumps to v1.1.7.
