[COST-1471] Create AWS Service/Region Resource Types

[Fozzywozzybear]

These two new endpoints show data from the service the user is running and also can show the regions the user has cloud services running. These two endpoints also support searching and ordered in ascending order.

Steps to test

1. Create and load test data
2. Go to http://localhost:8000/api/cost-management/v1/resource-types/aws-service/ adding ?search= to the end to search for the data, Example, ?search=AmazonEC will only show results with AmazonEc and order them in ascending order. You can also type in just ?search=ama and this will show results with the letters ama in them.
3. Go to http://localhost:8000/api/cost-management/v1/resource-types/aws-region/ adding ?search to the end to search for data, Example, ?search=EU will only show results that are from EU. You can also type in just E and this will show ressults with the letter E in them.
4. Note, this search is not case sensitive.
