Enhanced support for the non-default VRF management instance mgmt_junos

Syslog IPv6 addresses, RADIUS packets, and Automation scripts support the non-default VRF management instance mgmt_junos, when the management-instance statement is configured. For syslog, statements at the [edit system syslog] hierarchy level now support IPv6 addresses when connecting to a remote host or an archival site. RADIUS authentication, authorization, and accounting packets can be configured to use the mgmt_junos instance. Also, Automation (commit, event, JET, op, or SNMP) scripts now can be refreshed over the mgmt_junos instance. To enable the non-default VRF management instance, you must also configure the mgmt_junos routing instance at the [edit system routing-instances] hierarchy level.
