Make the Key Connector admin exemption configurable

Owners and admins no longer get the connector advertised by default
(KEY_CONNECTOR_EXEMPT_ADMINS=true), so clients ask them for a master
password instead of enrolling them. Setting it to false advertises it
to them as well. Users already enrolled keep unlocking through the
connector either way.
