[DefaultCodegenConfig] Handle default parameter values

[michaeldavis-wf]

Parameter default values are not being generated. This appears to be due to not copying the values from the Swagger Parameter object over to the Codegen Parameter object. I copied some of that logic from the master branch and updated it slightly.

Using this (partial) definition:

paths:
  /scim2/Users:
    get:
      summary: Retrieve users
      description: Retrieve a collection of user resources for the authorized organization.
      operationId: listUsers
      parameters:
        - name: startIndex
          description: An integer indicating the 1-based index of the first query result.
          in: query
          required: false
          schema:
            type: integer
            format: int32
            minimum: 1
            default: 1

Generated code used to look like:

@Parameter(in = ParameterIn.QUERY, description = "An integer indicating the 1-based index of the first query result.", schema=@Schema(allowableValues={  }, minimum="1")) @QueryParam("startIndex") Integer startIndex

And now looks like:

@Parameter(in = ParameterIn.QUERY, description = "An integer indicating the 1-based index of the first query result.", schema=@Schema(allowableValues={  }, minimum="1")) @DefaultValue("1") @QueryParam("startIndex") Integer startIndex
