Follow up bicep resource work

[davidfowl]

Following this issue #1941, we have some issues to work out:

1. Consider adding a bicep resource type #1941 (comment)
2. - Change secret handling to be keyvault based (Use keyvault for secret outputs #2131)
3. - Do outputs need to be expressed in the manifest in order for azd to create a single uber deployment?
4. - Consider allowing bicep files to come from a nuget package (Always copy the bicep files #2202 (comment))
5. - Add support for check summing the bicep for diffs in the provisioner (Azure Provisioning is not creating additional ServiceBus Queues after first run #2384)
6. - Bicep clean up.
7. - Add support for multi file bicep modules represented on disk (Add support for multiple bicep modules #2405)
8. - Tag azure resources with aspire-resource-name

I reviewed the bicep code in: https://github.com/dotnet/aspire/tree/main/src/Aspire.Hosting.Azure/Bicep

Here's my feedback:

1. resourceToken should be more unique, otherwise there will be collisions: var resourceToken = toLower(uniqueString(subscription().id, environmentName, location))

2. Use consistent naming for resources, I see camel and pascal

3. Consider adding a role.bicep like this:
   https://github.com/Azure/azure-dev/blob/main/templates/common/infra/bicep/core/security/role.bicep

4. Consider adding default retention and sku to appinsights.bicep/workspaces

5. cosmos is hardcoded to docdb, consider adding a param if you want to ever use the mongo api.
   https://github.com/Azure/azure-dev/blob/main/templates/common/infra/bicep/core/database/cosmos/cosmos-account.bicep#L10

6. Consider cosmos serverless as it is MUCH cheaper.
   https://github.com/Azure/azure-dev/blob/main/templates/common/infra/bicep/core/database/cosmos/cosmos-account.bicep#L30

7. consider adding kv secret bicep:
   https://github.com/Azure/azure-dev/blob/main/templates/common/infra/bicep/core/security/keyvault-secret.bicep

8. consider using amv module references instead of shipping bicep modules, the source is here:
   https://github.com/Azure/bicep-registry-modules/tree/main/avm/res
