Automatically unload the existing model when calling /load. This was
requested many times, and does make more sense in the long run.

This option saves some VRAM, but does have the chance to error out.
Add this in the experimental config section.

Returns token offsets, selected tokens, probabilities of tokens
post-sampling, and normalized probability of selecting a token
pre-sampling (for efficiency purposes).
Only for text completions. Chat completions in a later commit.

Split the get tokens function into separate wrapper encode and decode
functions for overall code cleanliness.

Many APIs automatically ask for request streaming without giving
the user the option to turn it off. Therefore, give the user more
freedom by giving a server-side kill switch.

Add the ability to use an unsafe config flag if needed and migrate
the exl2 check to a different file within the exl2 backend code.

Exllamav2 is currently supported on all GPUs and versions. Therefore,
it should be expected that users use the latest version of exllamav2 to
get the latest features.
Doing this helps reduce checks that don't really serve any purpose.

Allow users to switch the currently overriden samplers via the API
so a restart isn't required to switch the overrides.

Unify API sampler params into a superclass which should make them
easier to manage and inherit generic functions from.
Not all frontends expose all sampling parameters due to connections
with OAI (that handles sampling themselves with the exception of
a few sliders).
Add the ability for the user to customize fallback parameters from
server-side.
In addition, parameters can be forced to a certain value server-side
in case the repo automatically sets other sampler values in the
background that the user doesn't want.

Move common functions into their own folder and refactor the backends
to use their own folder as well.
Also cleanup imports and alphabetize import statments themselves.
Finally, move colab and docker into their own folders as well.

Previously, if model_name was commented out, a load would not occur.
Add the case if model_name or loras is blank which returns None when
parsing the YAML.

Add an argparser that casts over to dictionaries of subgroups to
integrate with the config.
This argparser doesn't contain everything in the config due to complexity
issues with CLI args, but will eventually progress to parity. In addition,
it's used to override the config.yml rather than replace it.
A config arg is also provided if the user wants to fully override the
config yaml with another file path.

Similar to the transformers library, add an error handler when an
exception is fired. This relays the error to the user.

These are commonly seen in huggingface provided chat templates and
aren't that difficult to add in.
For feature parity, honor the add_bos_token and ban_eos_token

This creates a massive security hole, but it's gated behind a flag

A warning will pop up when users disable authentication.

Non-streaming tasks were not regulated by the semaphore, causing these
tasks to interfere with streaming generations. Add helper functions
to take in both sync and async functions for callbacks and sequential
blocking with the semaphore.

Append generation prompts if given the flag on an OAI chat completion
request.
This appends the "assistant" message to the instruct prompt. Defaults
to true since this is intended behavior.

Jinja2 is a lightweight template parser that's used in Transformers
for parsing chat completions. It's much more efficient than Fastchat
and can be imported as part of requirements.
Also allows for unblocking Pydantic's version.
Users now have to provide their own template if needed. A separate
repo may be usable for common prompt template storage.

Generations can be logged in the console along with sampling parameters
if the user enables it in config.
Metrics are always logged at the end of each prompt. In addition,
the model endpoint tells the user if they're being logged or not
for transparancy purposes.

Sometimes fastchat may not be able to detect the prompt template from
the model path. Therefore, add the ability to set it in config.yml or
via the request object itself.
Also send the provided prompt template on model info request.
