Increases the test coverage of pkg/plugins.

take time.Duration instead of integers.

Brian Goff f2d384fca6 Fix deadlock on v1 plugin with activate error
When a plugin has an activation error, it was not being checked in the
`waitActive` loop. This means it will just wait forever for a manifest
to be populated even though it may never come.

Brian Goff 2938dce794 Fix race/deadlock in v1 plugin handlers
When a plugin is activated, and then `plugins.Handle` is called to
register a new handler for a given plugin type, a deadlock occurs when
for anything which calls `waitActive`, including `Get`, and `GetAll`.

This happens because `Handle()` is setting `activated` to `false` to
ensure that plugin handlers are run on next activation.
Maybe these handlers should be called immediately for any plugins which
are already registered... but to preserve the existing behavior while
fixing the deadlock, track if handlers have been run on plugins and
reset when a new handler is registered.

The simplest way to reproduce the deadlock with Docker is to add a `-v
/foo` to the test container created for the external graphdriver tests.
