Fix bug in chart config template

[manuelbuil]

Description

When installing flannel from the chart, if we don't quote that value, we get the error:

E0124 10:50:40.343650       1 main.go:226] Failed to create SubnetManager: error parsing subnet config: invalid character 'A' after object key:value pair

Because the config is:

  net-conf.json: |
    {
      "Network": "10.42.0.0/16",
      "Backend": {
        "VNI": 1,
        "MTU": 1500,
        "MacPrefix": 0E-2A,
        "Type": "vxlan"
      }
    }

i.e. the MacPrefix requires quotes
