Tokenizer loading process

[mitya52]

I found some problems with tokenizer loading:

• first request to any model causes problem with tokenizer, error looks like this {"detail":"Tokenizer: failed to load tokenizer: EOF while parsing an object at line 6253 column 15"}
• we should give path to tokenizer's data with model directly without "template": not all models stored in huggingface (3rd-party gpt model for example)
