Introduce LogURIGenerator helper function in cio package. It is used in
the restart options, like WithBinaryLogURI and WithFileLogURI.
And restart.LogPathLabel might be used in production and work well. In
order to reduce breaking change, the LogPathLabel is still recognized if
new LogURILabel is not set. In next release 1.5, the LogPathLabel will
be removed.

This cleans up persistent work dirs on TaskManager boot. These dirs can
be left behind in a machine reboot. The state in /run will not exist
but the work dir in the root does, we should cleanup work dirs when
tasks are not loaded.
This also improves error handling that would prevent the task manager
from loading when a single task fails to load or cleanup.
