This PR adds a `--ollama-url` option to `cli.py`, the lightweight
redis-cli-like tool that expands !"text" arguments into embeddings via
Ollama.
Previously, the embedding call was hardcoded to
http://localhost:11434/api/embeddings. With this change, users can
specify a custom Ollama server URL when starting the tool.
If no URL is provided, the tool defaults to what it was before.
The vector-sets module is a part of Redis Core and is available by default,
just like any other data type in Redis.
As a result, when building Redis from the source, the vector-sets module
is also compiled as part of the Redis binary and loaded at server start-up.
This new data type added as a preview currently doesn't support
all the capabilities in Redis like:
32-bit OS
C99
Short-read that might end with memory leak
AOF rewirte
defrag
