30f0fe0a84 Add "default" probe timeout logic for server readings check 
this way we don't have to set those timeouts on every single probe

1f8507508a Make dummy probe use tighter pattern for random readings 
to make for a more reasonable-looking graph

19553edda6 Add per-status timeouts and tracking for probe status 
i.e. this lets us keep track of when a probe becomes "high temp" and then later
if it becomes "critical high temp" we can still know how long it's been high

5830c7bd15 Fix logic bug when checking readings for client 
yikes! first probe whose readings were checked okay, was causing other probes
to just be skipped

3aa4185de9 Leverage common "now" value when sending emails from server 
i.e. don't generate new "now" when sending an email, just use the "now" we
established when starting to check the readings

b4c52319c6 Make client more tolerant of database restart 
note that a retry is *not* attempted within a given "take readings" run.
rather, client will consider that full readings take to have failed, if any
part of it fails.

but then we keep track of type/amount of some (database connection) failures,
and will suppress logging the full error for first 3 attempts.  in practice
this lets us recover from simple database restarts, and if database becomes
truly unavailable we'll hear about it shortly.

any other type of error is immediately logged on first failure.

76e40063ee Tweak server logic for checking client readings 
do not check readings for "archived" clients.  do not consider the client
"offline" unless it has *no* current probe readings.  previously we were
assuming offline if any probe readings were missing, even if some were found.

85e8ed9832 Log error when client probe takes a 185.0 reading 
this indicates some power issue with the probe(s) and does not really mean
that's the temperature.  so we don't want the server to send out "high temp"
email etc. but rather just a technical error email

18b224a3e0 Add Client.disk_type to track SD card vs. USB 
i.e. assuming raspberry pi device for the client.  kind of a specific use case
behind this but it seemed like it could be useful generally

152ea26c02 Add Client.archived flag, ignore archived for "disabled probes" check 
this lets us keep old client config around without deleting it, but it should
not interfere with other logic etc.
