## Description
### Refactoring
This PR refactors `invokeai.app.services.config` to be easier to
maintain by splitting off the argument, environment and init file
parsing code from the InvokeAIAppConfig object. This will hopefully make
it easier for people to find the place where the various settings are
defined.
### New Features
In collaboration with @StAlKeR7779 , I have renamed and reorganized the
settings controlling image generation and model management to be more
intuitive. The relevant portion of the init file now looks like this:
```
Model Cache:
ram: 14.5
vram: 0.5
lazy_offload: true
Device:
precision: auto
device: auto
Generation:
sequential_guidance: false
attention_type: auto
attention_slice_size: auto
force_tiled_decode: false
```
Key differences are:
1. Split `Performance/Memory` into `Device`, `Generation` and `Model
Cache`
2. Added the ability to force the `device`. The value of this option is
one of {`auto`, `cpu`, `cuda`, `cuda:1`, `mps`}
3. Added the ability to force the `attention_type`. Possible values are
{`auto`, `normal`, `xformers`, `sliced`, `torch-sdp`}
4. Added the ability to force the `attention_slice_size` when `sliced`
attention is in use. The value of this option is one of {`auto`, `max`}
or an integer between 1 and 8.
@StAlKeR7779 Please confirm that I wired the `attention_type` and
`attention_slice_size` configuration options to the diffusers backend
correctly.
In addition, I have exposed the generation-related configuration options
to the TUI:
### Backward Compatibility
This refactor should be backward compatible with earlier versions of
`invokeai.yaml`. If the user re-runs the `invokeai-configure` script,
`invokeai.yaml` will be upgraded to the current format. Several
configuration attributes had to be changed in order to preserve backward
compatibility. These attributes been changed in the code where
appropriate. For the record:
| Old Name | Preferred New Name | Comment |
| ------------| ---------------|------------|
| `max_cache_size` | `ram_cache_size` |
| `max_vram_cache` | `vram_cache_size` |
| `always_use_cpu` | `use_cpu` | Better to check conf.device == "cpu" |

## Description
[fix(stats): fix fail case when previous graph is
invalid](d1d2d5a47d)
When retrieving a graph, it is parsed through pydantic. It is possible
that this graph is invalid, and an error is thrown.
Handle this by deleting the failed graph from the stats if this occurs.
[fix(stats): fix InvocationStatsService
types](1b70bd1380)
- move docstrings to ABC
- `start_time: int` -> `start_time: float`
- remove class attribute assignments in `StatsContext`
- add `update_mem_stats()` to ABC
- add class attributes to ABC, because they are referenced in instances
of the class. if they should not be on the ABC, then maybe there needs
to be some restructuring

Please provide steps on how to test changes, any hardware or

On `main` (not this PR), create a situation in which an graph is valid
but will be rendered invalid on invoke. Easy way in node editor:
- create an `Integer Primitive` node, set value to 3
- create a `Resize Image` node and add an image to it
- route the output of `Integer Primitive` to the `width` of `Resize
Image`
- Invoke - this will cause first a `Validation Error` (expected), and if
you inspect the error in the JS console, you'll see it is a "session
retrieval error"
- Invoke again - this will also cause a `Validation Error`, but if you
inspect the error you should see it originates in the stats module (this
is the error this PR fixes)
- Fix the graph by setting the `Integer Primitive` to 512
- Invoke again - you get the same `Validation Error` originating from
stats, even tho there are no issues
Switch to this PR, and then you should only ever get the `Validation
Error` that that is classified as a "session retrieval error".
It is `"invocation"` for invocations and `"output"` for outputs. Clients may use this to confidently and positively identify if an OpenAPI schema object is an invocation or output, instead of using a potentially fragile heuristic.
Doing this via `BaseInvocation`'s `Config.schema_extra()` means all clients get an accurate OpenAPI schema.
Shifts the responsibility of correct types to the backend, where previously it was on the client.
Doing this via these classes' `Config.schema_extra()` method makes it unintrusive and clients will get the correct types for these properties.
Shifts the responsibility of correct types to the backend, where previously it was on the client.
The `type` property is required on all of them, but because this is defined in pydantic as a Literal, it is not required in the OpenAPI schema. Easier to fix this by changing the generated types than fiddling around with pydantic.
