should update docs for KUBECONFIG to make it work on Windows

should update docs for KUBECONFIG to make it work on Windows

[hoatle]

@hieptranquoc:

• it did not work on Windows (Cygwin), we need to find the root cause to fix this.
• need to check if it works on Windows (Git-Bash).

[hieptranquoc]

• in windows(Cygwin), please use:

cd workspace/inventory/artifacts
# and export
export KUBECONFIG=$KUBECONFIG:$(pwd)/admin.conf
# or export
export KUBECONFIG=$HOME/.kube/config:$(pwd)/admin.conf

this export not run in Cygwin:

export KUBECONFIG=$(pwd)/admin.conf

because it will add a direct path to env <<< the wrong path.

• Should check window firewall to accept the connection ( Cygwin on win 7 )
