snap store proxy configuration not getting applied on CAPI worker nodes

However, in the worker nodes, the cloud-init-output.log indicates that the worker did not have the snap store proxy configured:

+ /capi-scripts/00-configure-snapstore-http-proxy.sh  
+ [[ '' != '' ]]
+ [[ '' != '' ]]
+ /capi-scripts/00-configure-snapstore-proxy.sh  
+ '[' 2 -ne 2 ']'
+ '[' -z '' ']'
+ echo 'Using the default snapstore'
Using the default snapstore
+ exit 0

This feature works as expected on the control plane nodes.

It should be possible to configure the snap store proxy on the worker nodes as well.

Hi @vishvikkrishnan,

Could you please try again with version 0.6.9 of the providers? clusterctl init -i maas -b microk8s:v0.6.9 -c microk8s:v0.6.9.

The reason I ask is because I was not able to reproduce your issue with this version, everything worked fine.
