Elastic Memory Provider & Podcast Commands (#516)

## Elastic Memory Provider

This PR adds an implementation of an
[Elastisearch](https://www.elastic.co/) memory provider to the
`/examples/memoryProvider` directory. This memory provider uses the
existing implementations based on the filesystem for the object table
and the temporal table. In the future we hope to add support for these
to the elastic instance as well.

This implementation is built off of the `StorageProvider` interface
defined in the Knowledge Processor package.

In addition to the memory provider, two commands were added for
interacting with podcasts that have been indexed.
This pull request introduces significant updates to the memory
management system in the chat and podcast examples, primarily by
integrating Elasticsearch for enhanced storage capabilities.
Additionally, it includes various dependency updates and minor code
improvements.
