This commit adds a table 'device_skip' that is used to restrict job queue
searches to avoid jobs that are not permitted on this backend via *_no ACLs,
or jobs on devices that have previously encountered multiple SNMP timeouts.
When the backend loads or a device is added, a row is added to the table if
that device should not be polled on this backend (together with the job
actions which are to be skipped/denied). When a device SNMP connect fails a
counter in the same row (or a new row) is incremented.
There is also a new report 'SNMP Connect Failures' to show the devices with
non-zero SNMP connect failure counters. A configurable limit in the setting
'max_deferrals' is used to set the threshold of no longer polling the device.
To reset the deferrals/failures count, restart the Netdisco backend (which
regenerates 'device_skip' cache entries).
