Create V2 Auth Plugins

Extract the authentication code from a v2 client and move it to a series
of auth plugins. Auth plugins each represent one method of
authenticating with a server and there is a factory method on the base
class to select the appropriate plugin from a group of arguments.

When a v2 client wants to do authentication it will create
a new v2 auth plugin, do the authentication and then take that result
for the client to use.

Create V3 Auth Plugins

Extract the authentication code from a v3 client and move it to a series
of auth plugins. As v3 authentication can contain multiple
authentication methods this concept is represented by an AuthMethod. An
auth plugin then is provided with multiple mechanisms to authenticate
with.

There is also some helper class for the standard case where you only
need to authenticate with one method.

When a v3 client wants to do authentication it will create a new v3 auth
plugin, do the authentication and then take that result for the client
to use.
