Disable field type

Field visibility type

Fix issue with stale SQL connection pools consuming unneeded connections

remove `field_type` as a user presented/controllable thing.  only meaningful implication is that the list of fields for breakout becomes all fields by default now.

Report Timezone setting warning

provide a small warning about the Report Timezone on the settings page and the fact that it won't work on databases that don't have timezone support.

publish a `:database-update` event and create an event listener which calls our driver notify-database-updated method whenever we get a :database-update event.

add a new optional driver method for `notify-database-updated` which allows drivers to be informed when their databases are updated. then implement this method on the generic-sql driver and use it to actively shutdown any open connection pool on the updated database so that we can recreate it as needed.

update the connection-spec acquisition code for our generic SQL driver to unify it based on acquiring a connection for a given DATABASE and to replace the memoize/ttl with our own atom for caching db connection pools to each database.  This avoids the unnecessary recreation of connection pools every so many hours.

add a client side search on the table name in the data selector.
