Reproduce:

• Try to create an alert with a threshold above integer max value (e.g. 4838400000) via the rest api

Expected:

• 204 No Content response

Observed:

• 400 Bad Request response

Context:

• Since we store the value of duration reports as milliseconds, this number can be exceeded easily if a user wants to set a duration threshold of more than 25 days.

Hint:

• We should probably use long instead of int to store the threshold
• This might also affect the "Check report every" and "Reminder Emails" fields
