Linux Consumption functionapp should support WEBSITE_CONTENTSHARE

[Hazhzeng]

Since we implement a work around to disable WEBSITE_CONTENTSHARE and WEBSITE_CONTENTAZUREFILECONNECTIONSTRING for Linux Consumption functionapp creation (Azure/azure-cli#9027), we may still want to re-enable it when the backend is fixed.

Once the backend is fixed, we should

1. Stop removing WEBSITE_CONTENTSHARE and WEBSITE_CONTENTAZUREFILECONNECTIONSTRING appsettings when running "--build remote"
2. Stop removing WEBSITE_CONTENTSHARE and WEBSITE_CONTENTAZUREFILECONNECTIONSTRING appsettings in https://github.com/Azure/azure-cli

@ahmedelnably any movement on this? What's the holdup?

This should probably get re-looked at.
