update to 0.1, remove deprecated functionality and focus on api catalog backend

[mattf]

this is version 0.1.0 of the connectors with two primary changes -

1. [user visible] deprecated or unavailable functionality removed
2. [not use visible] use of api catalog (integrate.api.nvidia.com and ai.api.nvidia.com) instead of nvcf (api.nvcf.nvidia.com) for inference

all playground_* model endpoints have been decommissioned.

functionality removed -

• models: playground_mamba_chat, playground_smaug_72b, playground_nemotron_qa_8b, playground_nemotron_steerlm_8b, playground_steerlm_llama_70b, playground_yi_34b, playground_nvolveqa_40k
• methods: available_functions, get_available_functions, get_model_details, get_binding_model, mode, validate_model, validate_base_url, reset_method_cache, validate_client, aifm_deprecated, aifm_bad_deprecated, aifm_labels_deprecated, custom_preprocess, preprocess_msg, custom_postprocess, get_generation, get_stream, get_astream, get_payload, prep_payload, prep_msg, deprecate_max_length
• properties: ChatNVIDIA.bad, ChatNVIDIA.labels, ChatNVIDIA.infer_endpoint, ChatNVIDIA.client, ChatNVIDIA.streaming, NVIDIAEmbeddings.infer_endpoint, NVIDIAEmbeddings.client, NVIDIAEmbeddings.max_length

functionality deprecated -

• NVIDIAEmbeddings.model_type, instead of setting model_type="query" or "passage" use NVIDIAEmbeddings.embed_query and NVIDIAEmbeddings.embed_documents

migration guide -

• ChatNVIDIA().mode("nim", base_url="http://...") must use ChatNVIDIA(base_url="http://...")
• NVIDIAEmbeddings().mode("nim", base_url="http://...") must use NVIDIAEmbeddings(base_url="http://...")
• NVIDIARerank().mode("nim", base_url="http://...") must use NVIDIARerank(base_url="http://...")
• compatibility for the playground_nvolveqa_40k (aka nvolveqa_40k) model. when specifying model="nvolveqa_40k", the NV-Embed-QA model will be used and truncate="END" will be set. note: the old nvolveqa_40k model endpoint would silently truncated input while all available endpoints raise an error instead of truncating.

model migration, the following models will raise a warning and use an alternative (model changes in italics) -
