adopt single-port default vars in ziti create config

[qrkourier]

ziti create config controller still uses the default TCP port 6262 for the control plane. Now that we have ALPN, a better default is to use a single TCP port 1280 for all default TLS listeners.

@dovholuknf and I decided on a set of config option variables to represent this single port default for generating configs.

• controller
  • ZITI_CTRL_ADVERTISED_ADDRESS (default single address for ctrl plane and web listener unless the web listener is overridden by ZITI_CTRL_EDGE_ADVERTISED_ADDRESS; this changes the default for web listener from ZITI_NETWORK_NAME).
    • ZITI_CTRL_ADVERTISED_PORT (default single port for ctrl plane and web listener unless web listener is overridden by ZITI_CTRL_EDGE_ADVERTISED_PORT; this changes the default for ctrl plane to 1280)
• router
  • ZITI_ROUTER_ADVERTISED_ADDRESS (single address for edge, link, and web listeners; there are no override vars)
    • ZITI_ROUTER_PORT (single port for edge, link, and web listeners unless edge listener port is overridden by ZITI_ROUTER_LISTENER_BIND_PORT; this changes the default link listener from 10080 to 3022)
