API keys are not allowed to view all the admin's models, templates,
draft models, loras, etc. Basically anything that can be viewed
on the filesystem outside of anything that's currently loaded is
not allowed to be returned unless an admin key is present.
This change helps preserve user privacy while not erroring out on
list endpoints that the OAI spec requires.

Pass a request and internally unwrap the headers. In addition, allow
X-admin-key to get checked in an API key request.

Move OpenAPI export as an env var within the main function. This
allows for easy export by running main.
In addition, an env variable provides global and explicit state to
disable conditional wheel imports (ex. Exl2 and torch) which caused
errors at first.

If flash attention is already turned off by exllamaV2 itself, don't
try creating a paged generator. Also condense all the redundant
logic into one if statement.
Also check arch_compat_overrides to see if flash attention should
be disabled for a model arch (ex. Gemma 2)

Previously, the parameters under the "model" block in config.yml only
handled the loading of a model on startup. This meant that any subsequent
API request required each parameter to be filled out or use a sane default
(usually defaults to the model's config.json).
However, there are cases where admins may want an argument from the
config to apply if the parameter isn't provided in the request body.
To help alleviate this, add a mechanism that works like sampler overrides
where users can specify a flag that acts as a fallback.
Therefore, this change both preserves the source of truth of what
parameters the admin is loading and adds some convenience for users
that want customizable defaults for their requests.
This behavior may change in the future, but I think it solves the
issue for now.

Move the large import errors into the check functions themselves.
This helps reduce the difficulty in interpreting where errors are
coming from.

* Model: Clean up paged attention checks
* Model: Move cache_size checks after paged attn checks
Cache size is only relevant in paged mode
* Model: Fix no_flash_attention
* Model: Remove no_flash_attention
Ability to use flash attention is auto-detected, so this flag is unneeded. Uninstall flash attention to disable it on supported hardware.
* Model: More extensive checks for paged attention
Previously, TabbyAPI only checked for whether the user's hardware supports flash attention before deciding whether to enabled paged mode.
This adds checks for whether no_flash_attention is set, whether flash-attn is installed, and whether the installed version supports paged attention.
* Tree: Format
* Tree: Lint
* Model: Check GPU architecture first
Check GPU arch prior to checking whether flash attention 2 is installed
