Create privileged transport components

This commit allows transport servers to define the relevant components on the
XMPP server. Transports are configured by adding the following config to the
inventory's variables:

transports:
 - subdomain: a-example-legacy-network
   secret: a-long-randomly-generated-secret
 - subdomain: another-example-legacy-network
   secret: another-long-randomly-generated-secret

These are iterated over and a privileged component is created for each.
