There is a bug in the windows CI that causes a time difference between
the host and the container.

The locks now retry on the backend side to prevent clients from having
to round trip on locks that might be momentarily held. This exposed some
timing errors in the updated_at fields for content ingest, so we've had
to move that to a separate file to export the monotonic go runtime
timestamps.

While early PoCs had download resumption working, we didn't have tests
and had not verified the behavior. With this test suite, we now are able
to show that download resumption is properly supported in the content
store. In particular, there was a bug where resuming a download would
not issue the writes to the correct offset in the file. A Seek was added
to ensure we are writing from the current ingest offset.
In this investigation, it was also discovered that using the OS/Disk
created time on files was skewed from the monotonic clock in Go's
runtime. The startedat values are now taken from the Go runtime and
written to a separate file.

Content commit is updated to take in a context, allowing
content to be committed within the same context the writer
was in. This is useful when commit may be able to use more
context to complete the action rather than creating its own.
An example of this being useful is for the metadata implementation
of content, having a context allows tests to fully create
content in one database transaction by making use of the context.

Ensure all writers are closed at end of test for content
test suite. Prevents test from leaving lingering connections
to the content store.

Prevents potential race between garbage collector reading labels
after commit and labels getting set.
