This special endpoint can be used to help debug the wire protocol.
Instead of routing the request through the normal dispatch mechanism,
we instead read all frames, decode them, and feed them into our state
tracker. We then dump the log of all that activity back out to the
client.

Returns a list containing potential redirect targets that will be
advertised in capabilities data. Each dict MUST have the following
keys:
name
The name of this redirect target. This is the identifier clients use
to refer to a target. It is transferred as part of every command
request.
protocol
Network protocol used by this target. Typically this is the string
in front of the ``://`` in a URL. e.g. ``https``.
uris
List of representative URIs for this target. Clients can use the
URIs to test parsing for compatibility or for ordering preference
for which target to use.
The following optional keys are recognized:
snirequired
Bool indicating if Server Name Indication (SNI) is required to
connect to this target.
tlsversions
List of bytes indicating which TLS versions are supported by this
target.
By default, clients reflect the target order advertised by servers
and servers will use the first client-advertised target when picking
a redirect target. So targets should be advertised in the order the
server prefers they be used.

``name`` is the name of the wire protocol command being provided.
``args`` is a dict defining arguments accepted by the command. Keys are
the argument name. Values are dicts with the following keys:
``type``
The argument data type. Must be one of the following string
literals: ``bytes``, ``int``, ``list``, ``dict``, ``set``,
or ``bool``.
``default``
A callable returning the default value for this argument. If not
specified, ``None`` will be the default value.
``example``
An example value for this argument.
``validvalues``
Set of recognized values for this argument.
``permission`` defines the permission type needed to run this command.
Can be ``push`` or ``pull``. These roughly map to read-write and read-only,
respectively. Default is to assume command requires ``push`` permissions
because otherwise commands not declaring their permissions could modify
a repository that is supposed to be read-only.
``cachekeyfn`` defines an optional callable that can derive the
cache key for this request.
``extracapabilitiesfn`` defines an optional callable that defines extra
command capabilities/parameters that are advertised next to the command
in the capabilities data structure describing the server. The callable
receives as arguments the repository and protocol objects. It returns
a dict of extra fields to add to the command descriptor.
Wire protocol commands are generators of objects to be serialized and
sent to the client.
If a command raises an uncaught exception, this will be translated into
a command error.
All commands can opt in to being cacheable by defining a function
(``cachekeyfn``) that is called to derive a cache key. This function
receives the same arguments as the command itself plus a ``cacher``
argument containing the active cacher for the request and returns a bytes
containing the key in a cache the response to this command may be cached
under.
