NO TICKET: fix thing_id query parameter for /sensor

[jacob-a-brown]

Why

This PR addresses the following problem / context:

• the query parameter ?thing_id broke for /sensor because a sensor was no longer easily connected to a thing via a sample

How

Implementation summary - the following was changed / added / removed:

• The deployment table is now used as the intermediary

Notes

Any special considerations, workarounds, or follow-up work to note?

• This gets all sensors related to a thing, regardless of its installation status (installation_date/removal_date). Is this the behavior we want, or should it only retrieve sensors that are currently installed at a thing?
