Route path parameters cannot be retrieved easily

Investigative information

Please provide the following:

• Timestamp: 2018-09-15
• Function App version (1.0 or 2.0-beta): 2.0-beta
• Function App name: Local
• Function name(s) (as appropriate): test-list
• Invocation ID: Local
• Region: Local

Repro steps

1. Create sample function based on source code below
2. Hit api /api/list/product_a?validate=true

Expected behavior

I expected to have both query and path parameters:

{
  "params": {
    "product": "product_a"
  },
  "query": {
    "validate": "true"
  }
}

Actual behavior

Instead I have the params property containing the query parameters:

{
  "method": "POST",
  "url": "http://localhost:7071/api/list/product_a?validate=true",
  "headers": {
    "connection": "keep-alive"
  },
  "params": {
    "validate": "true"
  },
  "query": {},
  "get_body": ""
}

Known workarounds

I have created a branch based on dev to make some changes to the http binding code and it is available here.

Let me know if this is relevant for the project and I will make a PR for it.
