Permit the state of updates required to be changed based on number of updates available

[swampdogmash]

Currently the state is binary based on whether updates (or security updates) are available or not. It would be useful to allow the state to also be dependent on having a specific number of updates available - eg a text box to type a number in and a state if greater than that, as well as the binary value.

This way, we could be:
"WARN" if between 1 and 9 and CRITICAL above 10
"OK" if between 1 and 5 and WARN above 5
