Agent should not connect to contrail-dns when it doesnt have end of RIB

[Hari Prasad Killi]

When contrail-dns doesnt have end of RIB, connections from agent should not be successful. If the connection is closed and agent sends a re-subscribe to discovery after a few retries, agent may move to a contrail-dns which can provide service.

[Nipa (nipak)]

On master image, Agent has a list of all DNS publishers in the system as agent subscribes with instances=0. When Agent detects a TCP connection DOWN (as control-node was being upgraded), agent after a few retries will try other DNS Servers in the list. Note at this point the upgraded DNS Servers which may be in the publisher list( as ttl did not expire), may be able to accept TCP connections. These new TCP connections need to be closed if end-of-rib is not computed.

Support dynamic configuration update of named

An additional file contrail-named-base.conf will contain the base named configurtion
such as options stanza, key stanza, controls stanza and logging stanza.

All configs generated due to vdns configuration resulting in view stanza will be written
to contrail-named.conf

Before sending "reconfig" command to named, both the files will be merged
into contrail-named.conf

The above gives flexibility to user to update and apply changes without restarting
the dns daemon which generated the contrail-named.conf

An additional helper script(applynamedconfig.py) will merge the files and apply the
config(contrail-named-base.conf) to named daemon.

Porting to R2.21 as work-day wants to use DNS forward mode.

To persist the changes in contrail-named.conf while vdns are added/deleted or
subnets added/deleted we separate building of contrail-named into static portion
