LocalDiskStorageController was dependent on putility for TeePromise, but
since putility is a workspace module it's difficult for extensions to
access it (Puter backend core would need to expose it). Since TeePromise
itself is very small and will rarely (if ever) be changed I decided to
move it to a separate package on npm.
Begin work on LocalDiskStorageController in the `puterfs` extension.
This replaces LocalDiskStorageStrategy and LocalDiskStorageService from
the core. The `upload()` method is implemented to verify that it's
working.
This commit by itself will break other storage strategies. The next step
is to allow extensions to register storage controllers for puterfs. Part
of that work is done in this commit by emitting an event to register
storage controllers, but this commit does not include a way to
configure/select storage controllers.
