PSGI::Extensions: add a modified PSGI environment cleanup handlers proposal

This is an import of the proposal at
https://github.com/Plack/psgi-specs/wiki/Proposal%3A-PSGI-environment-cleanup-handlers
with the following changes:

 * Fixed various typos & grammar error

 * We now say that psgix.cleanup.handlers MUST be ArrayRef

   I don't see any reason for why a server would support cleanup mode but
   wouldn't be capable of initializing psgix.cleanup.handlers to []. Just
   make this a MUST since having the server initialize it is easier, and
   if it can't create an empty ArrayRef in $env at the start of the
   request it probably can't support Plack (or Perl) at all.

 * Add background on what the cleanup handlers are for

   I think it helps to add a bit of background here to be explicit about
   what this feature is for, and in particular make sure that servers
   aren't going to implement this in some blocking fashion while the
   client is still waiting on them.

In addition the pull request originally contained two new boolean
flags, see "PSGI::Extensions: add two new boolean flags to the cleanup
spec", but after discussing it with miyagawa we decided to drop that
part.
