[mitchdenny]

This PR adds Azure Cosmos via CDK usage is:

var cosmosdb = builder.AddAzureCosmosDBConstruct("cosmos").AddDatabase("cosmosdb");

Manifest output is:

    "cosmos": {
      "type": "azure.bicep.v0",
      "connectionString": "{cosmos.secretOutputs.connectionString}",
      "path": "cosmos.module.bicep",
      "params": {
        "keyVaultName": ""
      }
    },

Bicep produced is:

targetScope = 'resourceGroup'

@description('')
param location string = resourceGroup().location

@description('')

}

Deploying successfully via both AZD and Azure Provisioner. Just needs some tests tuned.

Can you use cosmosAccount.GetConnectionString? https://github.com/Azure/azure-sdk-for-net/blob/feature/cdk/sdk/provisioning/Azure.Provisioning/src/cosmosdb/CosmosDBAccount.cs#L81
