dts: use Pydantic in the configuration

This change brings in pydantic in place of warlock. Pydantic offers
a built-in model validation system in the classes, which allows for
a more resilient and simpler code. As a consequence of this change:

- most validation is now built-in
- further validation is added to verify:
  - cross referencing of node names and ports
  - test suite and test cases names
- dictionaries representing the config schema are removed
- the config schema is no longer used and therefore dropped
- the TrafficGeneratorType enum has been changed from inheriting
  StrEnum to the native str and Enum. This change was necessary to
  enable the discriminator for object unions
- the structure of the classes has been slightly changed to perfectly
  match the structure of the configuration files
- the test suite argument catches the ValidationError that
  TestSuiteConfig can now raise
- the DPDK location has been wrapped under another configuration
  mapping `dpdk_location`
- the DPDK locations are now structured and enforced by classes,
  further simplifying the validation and handling thanks to
  pattern matching
