ollama: internal client is no more up to date

[treywelsh]

The ollamaclient package is no more up to date.
We should remove it and use directly the official ollama client.
The Ollama API is also described here

There's probably a lot more but here's what I've noted so far:

• Some options are no more up to date:
  • UseNuma is removed by Implement linux NUMA detection ollama/ollama#6186
  • NumGQA, RopeFrequencyBase, RopeFrequencyScale are removed by use model defaults for num_gqa, rope_frequency_base and rope_frequency_scale ollama/ollama#1983
  • EmbeddingOnly is removed by Fix embeddings load model behavior ollama/ollama#2848
• There's now a second embeddings endpoint. The documentation say it supersede the older one.

I would like to be assigned to this issue in order to make a PR for this ASAP.

By the way, when looking at older issues about the ollama client in langchaingo it seems there's a bit of cleaning to do, for instance this issue has been solved but is still opened: #778

It's really great, when can I use it

I made small tests, it seems to works.
Feel free to give it a try on the development branch
