tested this on a kvm lab with a 1.24 cluster running this PR's provider
(83b07d4f). both methods work end to end.
LbCookie on port 80, SourceBased on port 8090. `cmk list
lbstickinesspolicies` for the two rules:
```
"methodname": "LbCookie", "params": {"cookie-name": "SERVERID",
"nocache": "true"}
"methodname": "SourceBased", "params": {"expire": "30m", "tablesize": "200k"}
```
router haproxy config:
```
listen 10_0_60_84-80
server 10_0_60_84-80_0 10.1.1.55:31150 check cookie 10_1_1_55-31150
server 10_0_60_84-80_1 10.1.1.153:31150 check cookie 10_1_1_153-31150
cookie SERVERID insert nocache
listen 10_0_60_85-8090
stick-table type ip size 200k expire 30m
stick on src
```
10 requests each, two app copies on separate nodes:
```
--- LbCookie, no cookie kept:
5 Hostname: whoami-589b5665ff-98l7m
5 Hostname: whoami-589b5665ff-llrqn
--- LbCookie, cookie kept:
10 Hostname: whoami-589b5665ff-llrqn
--- SourceBased, same client:
10 Hostname: whoami-589b5665ff-llrqn
```
setting `cookie-name=APPID` replaced the policy (`set-cookie:
APPID=10_1_1_55-31150`). removing the annotation removed the policy and
requests split again.
bad input fails and cloudstack is left as is:
```
stickiness method LbCookie only works on plain HTTP ports: set appProtocol:
http on them
stickiness method "Bogus" in annotation
service.beta.kubernetes.io/cloudstack-load-balancer-stickiness-method-name is
not supported on this network
```
