Documentation: explicit connection of CLI after reload if https is changed to http

If user add https support to CLI, CLI reconnects from 9990 to 9993 port automatically:

• /core-service=management/security-realm=ManagementRealm/server-identity=ssl:add(keystore-path=management.keystore,keystore-relative-to=jboss.server.config.dir,keystore-password=password,alias=server,key-password=password,generate-self-signed-certificate-host=localhost)
  /core-service=management/management-interface=http-interface:write-attribute(name=secure-socket-binding,value=management-https)
  reload
  

• Press 'P'

But if user remove https support and want to use 9990 again, he needs to connect CLI to server explicitly

• /core-service=management/management-interface=http-interface:write-attribute(name=secure-socket-binding)
  /core-service=management/security-realm=ManagementRealm/server-identity=ssl:remove()
  reload
  connect
