RFC5549 allows IPv6 Next Hop address for the advertisement of IPv4
related NLRIs for <AFI/SAFI> of <1/1>, <1/2>, <1/4> and <1/128>.
Currently, the advertisement using the MP_REACH_NLRI is supported,
but IPv4 routes with IPv6 Next Hop is not enough.
This patch enable to advertise IPv4 routes for <AFI/SAFI> of <1/1>
through GoBGP CLI command.
e.g.)
$ gobgp global rib add -a ipv4 10.2.1.0/24 nexthop 2001:2::1

we use the term replace-peer-as instead of as-override
since openconfig is using it.
cli
```
$ gobgp n add <neighbor-addr> as <asn> replace-peer-as
```
config
```
neighbor:
config:
peer-as: <asn>
neighbor-address: <neighbor-addr>
as-path-options:
config:
replace-peer-as: true

RFC4271 9.1.2 Phase 2: Route Selection
If the AS_PATH attribute of a BGP route contains an AS loop, the BGP
route should be excluded from the Phase 2 decision function. AS loop
detection is done by scanning the full AS path (as specified in the
AS_PATH attribute), and checking that the autonomous system number of
the local system does not appear in the AS path. Operations of a BGP
speaker that is configured to accept routes with its own autonomous
system number in the AS path are outside the scope of this document.
Also this commit adds support for allow-own-as option to relax this.

For configuring the Nexthop Tracking features with ZClient, this patch
adds the config values:
- "nexthop-trigger-enable" enables to the Nexthop Tracking features.
Please note this features is only available with version 3 or later,
and "true" by the default with that version.
- "nexthop-trigger-delay" specifies the delay sec to update the
nexthops triggered by the events from Zebra daemon. The default is
5 secs and the same with the default of Cisco's routers.

This patch adds "--reason" option support into the disable neighbor command
which can specify "Administrative Shutdown Communication" on the BGP Cease
NOTIFICATION message.
Usage:
$ gobgp neighbor <neighbor address> disable --reason "some messages"

When we use gRPC API to add neighbor. Even if we specify,
config.Neighbor.AfiSafis parameter, it is ignored in
NewPeerFromConfigStruct(). Adding to that even if we fix the issue,
NewNeighborFromAPIStruct() count Families twice. So resulting neighbor
has duplicated Families configuration. This patch fixed both problems.
AdjRibOut isn't in memory so needs to be calculated on the fly.
Doing such for multiple neighbors consumes too much CPU (especially
there are lots of routes).

policy can have multiple statements. In each statement, when condition
is matched, route-action is finally evaluated after actions with mods.
When route-action is 'none', we contine to next statement if it exists.
When route-action is 'accept' or 'reject', we stop proceeding.
This patch fixes a bug that route-action can't be set to 'none' which
means route-action always be set to 'accept' or 'reject' and can't proceed
to the next statement.
