IDP-1518 Mount certificate store from Azure File Share rather than Azure Key Vault

[starcraft66]

Description of changes

Now that we have build a complete certificate store for Workleap containers, cannot fit in a Key vault for 2 reasons:

• Key vaults cap at 25/50KiB depending on the SKU and our certificate store is larger than that
• Key vaults can only store a single certificate and our store contains hundreds

The complete certificate store can now be mounted from the Azure File share it is located in.

Breaking changes

Reworked the helm values for the certificate store as the Azure Files CSI driver requires more information than the Key Vault CSI driver.

Additional checks

Tested using server-side dry-run on a dev cluster:

PS C:\Users\tristan.g-hane\src\gsoft-helm-charts> helm template --set certificateStore.enabled=true test ./charts/aspnetcore --debug | kubectl apply --dry-run=server -f -
install.go:218: [debug] Original chart version: ""
install.go:235: [debug] CHART PATH: C:\Users\tristan.g-hane\src\gsoft-helm-charts\charts\aspnetcore
