Add Qdrant container

This commit adds a qdrant container to the list of supported
Testcontainers.

The qdrant container allows configuration of:

- an API key to authenticate to Qdrant
- an x509 certificate used to secure communication to Qdrant with
  Transport Layer Security
- a custom configuration file. See
  https://qdrant.tech/documentation/guides/configuration/

Closes testcontainers#992
