This avoids some apparently otherwise unsolveable problems involving
races that resulted in the manifest listing bundles that were deleted.
Removed the annex-max-git-bundles config because it can't actually
result in deleting old bundles. It would still be possible to have a
config that controls how often to do a full push, which would avoid
needing to download too many bundles on clone, as well as needing to
checkpresent too many bundles in verifyManifest. But it would need a
different name and description.
I hope to support importtree=yes eventually, but it does not currently
work.
Added remote.<name>.allow-encrypted-gitrepo that needs to be set to
allow using it with encrypted git repos.
Note that even encryption=pubkey uses a cipher stored in the git repo
to encrypt the keys stored in the remote. While it would be possible to
not encrypt the GITBUNDLE and GITMANIFEST keys, and then allow using
encryption=pubkey, it doesn't currently work, and that would be a
complication that I doubt is worth it.
Changed the format of the url to use annex: rather than annex::
The reason is that in the future, might want to support an url that
includes an uriAuthority part, eg:
annex://foo@example.com:42/358ff77e-0bc3-11ef-bc49-872e6695c0e3?type=directory&encryption=none&directory=/mnt/foo/"
To parse that foo@example.com:42 as an uriAuthority it needs to start with
annex: rather than annex::
That would also need something to be done with uriAuthority, and also
the uriPath (the UUID) is prefixed with "/" in that example. So the
current parser won't handle that example currently. But this leaves the
possibility for expansion.

And document remote.<name>.git-remote-annex-max-bundles which will
configure it.
datalad-annex uses a similar url format, but with some enhancements.
See https://github.com/datalad/datalad-next/blob/main/datalad_next/gitremotes/datalad_annex.py
I added the UUID to the URL, because it is needed in order to pick out which
manifest file to use. The design allows for a single key/value store to have
several special remotes all stored in it, and so the manifest includes
the UUID in its name.
While datalad-annex allows datalad-annex::<url>?, and allows referencing
peices of the url in the parameters, needing the UUID prevents
git-remote-annex from supporting that syntax. And anyway, it is a
complication and I want to keep things simple for now.
