[STACK-2609][vcs negotiate state]Provide proper API to handle ACOS version

Description

a10-octavia side changes: https://github.com/a10networks/a10-octavia/pull/466

Jira Ticket

https://a10networks.atlassian.net/browse/STACK-2322 https://a10networks.atlassian.net/browse/STACK-2609

Technical Approach

In ACOS 5.2.1-p2, ACOS provide VCS handshaking status information in vcs summary. Therefore, a10-octavia can use this to check if VCS handshaking is ready. And following a10-octavia operations on vThunders will not be overwrite or removed by VCS reload or configuration merging.

aXAPI:  GET /axapi/v3/vcs/vcs-summary/oper

{ 
  "vcs-summary": { 
    "oper" : { 
      "vcs-handshake-completed-list": [ 
        { 
          "vcs-handshake-completed-id":2, 
          "vcs-handshake-completed":1 
        } 
      ], 
    }, 
  } 
}

Test Cases

create 2 LB with different subnet, and check ACOS side after finished


openstack loadbalancer create --vip-subnet-id tp91 --name vip1
openstack loadbalancer create --vip-subnet-id tp92 --name vip2
