Autorest plugin configuration

• Please don't edit this section unless you're re-configuring how the powershell extension plugs in to AutoRest AutoRest needs the below config to pick this up as a plug-in - see https://github.com/Azure/autorest/blob/main/docs/developer/architecture/AutoRest-extension.md

ModelFour Options

You can specify the following options in your configuration for modelerfour:

```yaml
modelerfour:
  # this will speed up the serialization if you explicitly say you do or do not want yaml tags in the model
  # default - both
  emit-yaml-tags: undefined|true|false

  # this will flatten modelers marked with 'x-ms-client-flatten'
  # defaults to false if not specified
  flatten-models: false|true

  # this will flatten parameters when payload-flattening-threshold is specified (or marked in the input spec)
  # defaults to false if not specified
  flatten-payloads: false|true

  # setting this to false will skip parameter flattening
  # for operations that have multiple requests (ie, JSON and BINARY)
  multiple-request-parameter-flattening: true|false

  # this runs a pre-namer step to clean up names
  # defaults to true if not specified
  prenamer: true|false

  # relaxes schema duplication checks to allow schemas with the
  # same name and renames duplicate schema names with a suffix
  # of "AutoGenerated" with an additional numeric suffix if more
  # than 2 duplicates of the same name are detected.
  #
  # defaults to false if not specified.
  #
  # NOTE: This parameter is a temporary workaround and will be
  # removed in a future release!
  lenient-model-deduplication: false|true

  # does a check to see if names in schemas/enums/etc will collide
  # off by default
  resolve-schema-name-collisons: false|true

  # if you want to keep the flattened models even if they are not used
  # off by default
  keep-unused-flattened-models: false|true

  # merges response headers into response objects
  # defaults to false if not specified
  # not implemented
  merge-response-headers: false|true

  # enables parameter grouping via x-ms-parameter-grouping
  # defaults to false if not specified
  group-parameters: false|true

  # some additional sanity checks to help debugging
  # defaults to false
  additional-checks: true|false

  # always create the content-type parameter for binary requests
  # when it's only one possible value, make it a constant.
  always-create-content-type-parameter: false|true

  # always create the Accept parameter
  always-create-accept-parameter: true|false

  # always create SealedChoiceSchema for x-ms-enum schemas no matter
  # what the settings are.  This can be used to smooth migration from
  # remodeler to modelerfour.
  always-seal-x-ms-enum: false|true

  # In the case where a type only definition is to inherit another type remove it.
  # e.g. ChildSchema: {allOf: [ParentSchema]}.
  # In this case ChildSchema will be removed and all reference to it will be updated to point to ParentSchema
  remove-empty-child-schemas: false|true

  # Prevent the given headers from being handled automatically. Instead they will remain as parameters.
  skip-special-headers: string[]

  # List of header names that shouldn't be included in the codemodel.
  # Those header would already be handled by the generator.
  ignore-headers: string[]

  # Make content-type property extensible for binary requests.
  content-type-extensible: false|true

  # **TEMPORARY FLAG DO NOT DEPEND ON IT**
  # Disable anyobject type and default to type any instead.
  # This is a temporary flag to smooth transition. It WILL be removed in a future version.
  treat-type-object-as-anything: false|true

  # **TEMPORARY FLAG DO NOT DEPEND ON IT**
  # Enable older inconsistent behavior that an enum with a single value would become a constant by default.
  seal-single-value-enum-by-default: false|true

  # customization of the identifier normalization and naming provided by the prenamer.

  # snake|snakecase - multi_word_identifier
  # upper|uppercase - MULTI_WORD_IDENTIFIER
  # kebab|kebabcase - multi-word-identifier
