out_azure_blob: Auto create container

**Is your feature request related to a problem? Please describe.**
When I set the option to auto create a container in the Azure Blob, I get an error telling me it does not exist

**Describe the solution you'd like**
Allow the creation of the container automatically.

**Additional context**
The change would be done inside the `plugins/out_azure_blob/azure_blob.c` file inside the `cb_azure_blob_ingest()` and `ingest_all_chunks()` methods

Read plugins/out_azure_blob/azure_blob.c, starting with cb_azure_blob_ingest() and ingest_all_chunks(). Trace how the auto-create-container option is handled and where the missing-container error occurs. Done means the configured Azure Blob container is created automatically before ingestion when it does not exist.
