This commit adds CLI support for addresses to be attached directly to a
Target, for all current types of Target (ssh and tcp).
It also clarifies the relevant documentation regarding the autogen of
API option functionality.
This add the generated code and additional configuration to support
sending the ssh target subtype to the api via the sdk or cli.
The cli now supports an additional subcommand for the ssh target
subtype:
boundary targets create ssh
boundary targets update ssh
