Support for min and max value validation

[dikhan]

Is your feature request related to a problem?

Currently maximum and minimum attributes are not supported in the provider, hence terraform configuration may contain invalid values which will end up being posted to the API, and the API would return an error. This feature requests adds support for both

prefix_length_v2:
  maximum: 28
  minimum: 25
  type: integer

Describe the solution you'd like

When the openapi terraform provider runs into a property that has max and min described, those should be added to the validation function for that property in the provider schema configuration so if the user terraform config contains non valid errors Terraform will fail upfront without the need to make and API call.

Acceptance criteria

ValidateFunc for a property containing maximum and minimum attributes would apply expected validation on the value inout by the user. If the value is not valid, terraform should return an error.
