Renamed execute(url:) methods such that the HTTP method is the first argument in the parameter list

Motivation:

If these are intended to be general methods for building simple requests, then it makes sense to have the method be the first parameter in the list.

Modifications:

Moved the `method: HTTPMethod` parameter to the front of the list for all `execute([...] url: [...])` methods, and made it default to .GET. I also changed the url parameter to be `urlPath` for the two socketPath based execute methods.

Result:

A cleaner public interface for users of the API.

 Connecting to servers bound to socket paths is easy:
 ```swift
 let httpClient = HTTPClient(eventLoopGroupProvider: .createNew)
-httpClient.execute(socketPath: "/tmp/myServer.socket", url: "/path/to/resource", method: .GET).whenComplete (...)
+httpClient.execute(.GET, socketPath: "/tmp/myServer.socket", urlPath: "/path/to/resource").whenComplete (...)
 ```
 
 Connecting over TLS to a unix domain socket path is possible as well:
 ```swift
 let httpClient = HTTPClient(eventLoopGroupProvider: .createNew)
-httpClient.execute(secureSocketPath: "/tmp/myServer.socket", url: "/path/to/resource", body: .string("hello"), method: .POST).whenComplete (...)
+httpClient.execute(.POST, secureSocketPath: "/tmp/myServer.socket", urlPath: "/path/to/resource", body: .string("hello")).whenComplete (...)
 ```
 
 Direct URLs can easily be contructed to be executed in other scenarios:
