Changing the maximum number of milliseconds that a pool can be idle
before being terminated, Setting it to a low value so that it gets
terminated and we don't get failures after the vm resumes.
This change attempts at solving the issue of the application being woken
up after suspension and being unable to talk to the LastFm API (i.e.
throwing plenty of Mint/timeout errors).
The theory is that with this setting the application should quickly
enough restart the pool after waking up.
