Remove kubeconfigdir. Use a tempfile instead
Kubeconfigdir does not need to be a configurable parameter. We just create a local file and use that to create the config after which it is not needed. Issue-ID: MULTICLOUD-614 Change-Id: I2df561d50b620e24c5ae5266b7200210e0c11caf Signed-off-by: Kiran Kamineni <kiran.k.kamineni@intel.com>
