When using CatsResource with Specs2, if the resource acquisition raises an exception, the tests will never start and the exception will never be reported.

Basically, if an exception is raised when acquiring the
val resource: Resource[F, A], it would previously be swallowed by the Future launched bybeforeAll. Due to the exception, the gate is never closed (i.e., theDeferredis never completed), so theDeferred#getcall inwithResourcenever completes.This PR puts a timeout on the
Deferred#getcall inwithResourceto avoid waiting forever. It also updatesvar valueto maybe containEither[Throwable, A], so that the exception raised in the acquisition phase is raised in the test, so that the user can see the details of the exception and hopefully resolve the underlying issue.
