Bug Description

Schema transformer automatically creates and maintains a full mesh of
bgp-peerings between all bgp-router objects that are in the same AS.
This includes taking care of cases where global AS number is changed
or a bgp-router object's AS number is changed.

This behavior is not desirable in cases where control-nodes peer with
route reflectors.

Proposal is to add a configuration knob in the global system config to
control this behavior. Default behavior will be to not mesh bgp-routers
automatically.

If the new knob is configured, schema transformer will implement the
current behavior. We will add fab support to set the new configuration
knob. Provisioning scripts provision_mx and provision_control will be
modified to honor the knob as well.

From what I understand, API clients such as webui and/or are already auto-meshing controllers, with all supported address families:

Shoudln't schema transformer configure all these AF too? Or never auto-mesh controllers at all, as API clients are already taking care of that:
