Interlock fails to start in polling mode if time unit not specified

[demaniak]

Setting PollInterval = "5" results in interlock failing to startup.
Log output:

FATA[0000] time: missing unit in duration 5

Setting PollInterval = "5s" lets interlock start up, but I have no idea if this is a correct time unit.

Suggest documentation be updated/expanded to mention the required time unit (and available viable options)?

Also, if possible perhaps default to seconds if no time unit specified?

Currently running interlock:test.

IMO the default time should be in milliseconds because the default polling interval is set in ms:

interlock/server/server.go

Line 29 in 08446f5

defaultPollInterval = time.Millisecond * 2000

I actually think we should change the default poll as too quick could cause issues. We should default it to seconds (2s). We could then add it if missing.
