Pinecone standalone refactoring (#2685)

This refactors the `dendrite-demo-pinecone` executable so that it:

1. Converts the old `.key` file into a standard `.pem` file
2. Allows passing in the `--config` option to supply a normal Dendrite configuration file, so that you can configure PostgreSQL instead of SQLite, appservices and all the other usual stuff
