Allow partial name match for `service ls --filter`

This fix tries to address the issue raised in 24270 where it was
not possible to have a partial name match when list services
with name filter.

This fix updates swarmkit and allows prefix search when name is
provided as the filter for listing services.

An additional integration test is added to cover the changes.

This fix fixes 24270.

Note: A separate pull request will be opened on swarmkit.
