vty: Add logging_vty_add_deprecated_subsys
This function permits the user to register deprecated log categories,
which will ensure that if log categories are removed from a program,
old config files will still load.
We simply dynamically allocate a cmd_element and install it at
CFG_LOG_NODE. Not registering it at VIEW_NODE or ENABLE_NODE
ensures that it's not accessible from the interactive VTY, but only
from the config file / configure node.
