Move more things out of FrigateApp (#13897)
* Moved FrigateApp.init_config() into FrigateConfig.load()

* Move frigate config loading into main

* Store PlusApi in FrigateConfig

* Register SIGTERM handler in main

* Ensure logging is setup during config parsing

* Removed pointless try

* Moved config initialization out of FrigateApp

* Made FrigateApp.shm_frame_count into a function

* Removed log calls from signal handlers

python's logging calls are not re-entrant, which caused at least one of
these to deadlock randomly.

* Reopen stdout/err on process fork

This helps avoid deadlocks (https://github.com/python/cpython/issues/91776).

* Make mypy happy

* Whoops. I might have forgotten to save.

Truly an amateur mistake.

* Always call FrigateApp.stop()

Removed usage of PyYAML for config parsing. (#13883)
* Ignore entire __pycache__ folder instead of individual *.pyc files

* Ignore .mypy_cache in git

* Rework config YAML parsing to use only ruamel.yaml

PyYAML silently overrides keys when encountering duplicates, but ruamel
raises and exception by default. Since we're already using it elsewhere,
dropping PyYAML is an easy choice to make.

* Added EnvString in config to slim down runtime_config()

* Added gitlens to devcontainer

* Automatically call FrigateConfig.runtime_config()

runtime_config needed to be called manually before. Now, it's been
removed, but the same code is run by a pydantic validator.

* Fix handling of missing -segment_time

* Removed type annotation on FrigateConfig's parse

I'd like to keep them, but then mypy complains about some fundamental
errors with how the pydantic model is structured. I'd like to fix it,
but I'd rather work towards moving some of this config to the database.

Make logging code self-contained (#13785)
* Make logging code self-contained.

Rewrite logging code to use python's builting QueueListener, effectively
moving the logging process into a thread of the Frigate app.

Also, wrap this behaviour in a easy-to-use context manager to encourage
some consistency.

* Fixed typing errors

* Remove todo note from log filter

* Do not access log record's msg directly
