Turbo Server version should be discovered

[evat-pm]

the kubeTurbo pod references a config file that contains information about the Turbo server including version like this:

/etc/kubeturbo/evaconfig
"serverMeta": {
"version": "6.0.2-SNAPSHOT",

however this explicit setting means that if the Turbo server is updated (changes version), kubeTurbo will fail connection, and the negotiation failure message is not logged. Could we discover the Turbo server version, and then determine if it is a supported version for the kubeTurbo image (defined in the yaml) to have the container be more flexible to the supported versions of Turbo server?

Enlin mentioned that there is an API to get this version:

curl -X GET --header “Accept: application/json” “https://<IP_TURBO>/vmturbo/rest/admin/versions”
