feature: Configurable "MountPath" for playbook cmd in "Pod Template" of ClusterOperation job

[geneliu]

1 Code requirement

Kubean uses hard-coded -i /conf/hosts.yml so there is no way to consume kubespray existing group_vars under inventory

2 observe opensource license

announce license at the beginning of file

3 sign-off your commit

your commit must be signed off

4 Is your feature request related to a problem? Please describe.

The customization under /kubespray/inventory/my-inventory/group_vars can not be used by clusteroperation job (pod)

5 Describe the solution you'd like
Our existing use case is like:

1. container image is based on kubespray with extra inventory (/kubespray/inventory/my-inventory) contents (group_vars ...)
2. playbook launch: ansible-playbook -i /kubespray/inventory/my-inventory/hosts.yml cluster.yml -e ...

An ideal solution/feature would be supporting configurable "MountPath":

kubean/pkg/util/entrypoint/entrypoint.go

Line 109 in 0738d5d

playbookCmd := "ansible-playbook -i /conf/hosts.yml -b --become-user root -e \"@/conf/group_vars.yml\""

kubean/pkg/controllers/clusterops/controller.go

Line 401 in 0738d5d

MountPath: "/conf/hosts.yml",

6 Describe alternatives you've considered

multiple vars config to be configured. So the varsConfRef is a list instead.

varsConfRef:
-   namespace: kubean-system
     name: cluster1-all-vars-conf
-   namespace: kubean-system
     name: cluster1-k8s-cluster-vars-conf
-   namespace: kubean-system
     name: cluster1-etcd-vars-conf
