kstone-dashboard supports yaml/json files export in visualization tool

[lianghao208]

Let's say kubernetes cluster stores resources in default namespace.
If users need to get data from default namespace:

1. Searching for key default in Visualization Tool
2. The result key would be:
   /{cluster prefix}/{api group name}/{resource name}/default/

Out of curiosity, how could you use the exported data?

This is an example:
Users need to recover data which has been deleted before, and the data has backup in a snapshot.

1. Create a new cluster from the snapshot.
2. Import the new cluster into kstone.
3. Export the data and recreate it in the original etcd cluster to recover.

kubectl create -f exported-data.yaml
