Add visit argument to updateTelStatus

The tel_status table has a visit column, and rows are inserted by the gen2Actor's updateTelStatus command, which uses the gen2Actor's internal/latest visit value. But gen2Actor's visit is updated when new FPS/MCS/SPS exposures are started, which can happen before an SPS visit finishes. Which then breaks queries for all ag status for a given SPS visit.

Add a visit= argument to updateTelStatus, so that the agcc, ag, and mcs actors can correctly group their status rows.

One gotcha. The gen2Actor also maintains a sequence number for the rows within a visit. Need to figure out what to do about that.
