7ef2f0bb82 Add CommunityCount BGP Policy Condition 
This is intended to have the same behaviour as [these OpenConfig paths](https://openconfig.net/projects/models/schemadocs/yangdoc/openconfig-routing-policy.html#routing-policy-policy-definitions-policy-definition-statements-statement-conditions-bgp-conditions-community-count):

c593d7c8b3 switch to Go API v2 for protobuf 
seems that sticking to Go API v1 for protobuf is headache for projects
using GoBGP.

This breaks the compatibility so bumps up the major version to 3.

27b80a935b bgp: Implement BGP link-bandwidth extended community 
Receiving
=========

Extended communities sent from FRR side:

```
route-map lb permit 10
 set extcommunity bandwidth 10
 set extcommunity soo 65001:123
exit
```

On GoBGP side it's decoded as 125000 as IEEE floating-point.

```
% sudo ./gobgp global rib 192.168.100.1/32 --json | jq '."192.168.100.1/32"'

    "source-id": "192.168.100.2",
    "neighbor-ip": "192.168.10.123"
  }
]
```

Sending
=======

When sending from GoBGP side:

```
[[policy-definitions]]
    name = "policy1"
    [[policy-definitions.statements]]
        [policy-definitions.statements.actions.bgp-actions.set-ext-community]
			options = "replace"
			[policy-definitions.statements.actions.bgp-actions.set-ext-community.set-ext-community-method]
				communities-list = ["lb:65021:125000"]

```

We get properly encoded/decoded in FRR as well:

```
~# vtysh -c 'show ip bgp 10.33.0.0/16 json' | grep 'LB:'
        "string":"RT:300:400 SoO:100:200 LB:65021:125000 (1.000 Mbps)"
```

94d720ff40 Add FQDN capability 
It's not kinda RFC (draft), but it's implemented and used in various
other open-source software like FRRouting, Bird, ExaBGP.

It's very handy when dealing with lots of peers.

Exampe between GoBGP and FRRouting:
```
% ./cmd/gobgp/gobgp neighbor 192.168.10.123 | grep -A4 fqdn:
    fqdn:       advertised and received
      Local:
         name: donatas-pc, domain:
      Remote:
         name: exit1-debian-9, domain:
```

```
% vtysh -c 'show bgp neighbors 192.168.10.17 json' | jq .'"192.168.10.17".neighborCapabilities.hostName'
{
  "advHostName": "exit1-debian-9",
  "advDomainName": "n/a",
  "rcvHostName": "donatas-pc",
  "rcvDomainName": "n/a"
}
