Added an explicit 'environment' option to allow for, basically, existing
behavior, where we don't mess with the environment variable at all,
though I kept the default as MEMORY since I don't think it's really
typical that folks actually want regular user backends to inherit the
credential cache of the server.

Added a few more tests and updated the documentation too.  Sadly, seems
we've missed the deadline for v15 though for lack of feedback on these.
Would really like to get some other folks commenting as these are new
pg_hba and postgresql.conf options being added.

Thanks!

Stephen
