Create an endpoint that returns properties based on a postcode parameter.

The uri should be /property?postcode={postcode}
And should return a list of properties within that postcode. 

Each property should have an id, priceIndicator, displayAddress, and type.

priceIndicator should be 
LOW for prices less than £500,000
MEDIUM for prices less than £1,000,000
HIGH for prices above that

displayAddress should be a single string

A sample response is:

{
 "properties": [
 {
 "id": 1,
 "priceIndicator": "LOW",
 "displayAddress": "2, Richard Lane, London, W1F 3ER",
 "type": "DETACHED"
 },
 {
 "id": 19,
 "priceIndicator": "HIGH",
 "displayAddress": "1, Value Road, London, W1F 3ER",
 "type": "SEMI_DETACHED"
 }
 ]
}```
