Use correct Poetry config when collecting Poetry projects

When collecting Poetry projects for caching, a '**/poetry.lock' glob is
used.  However, in order to process the Poetry configuration, the
"poetry" command is run from the repo's root directory; this causes
Poetry to return an invalid configuration when there is a Poetry project
inside an inner directory.

Instead of running a single Poetry command, glob for the same pattern,
and run a Poetry command for every discovered project.
