better query parameters handling

[baywet]

Summary

This PR provides better query parameters handling for all languages:

• Makes them optional
• Adds overrides for optional parameters in Java
• Better declaration in TypeScript to avoid needing a callback

Samples

Java

Existing

public java.util.concurrent.Future<Object> PostAsync(@javax.annotation.Nonnull final java.util.function.Consumer<PostQueryParameters> q) { return null; }

Additional

public java.util.concurrent.Future<Object> GetAsync() { return null; }

TypeScript

Before

public readonly GetAsync = (q: (options?: {select?: string[];
                    expand?: string[]}) => void) : Promise<object> => { return Promise.resolve({}); }

Now

public readonly GetAsync = (q?: {
                        select?: string[],
                        expand?: string[]
                        } | undefined) : Promise<object> => { return Promise.resolve({}); }

CSharp

Before

public Task<object> GetAsync(Action<GetParameters> q) { return null;}

Now

public Task<object> GetAsync(Action<GetParameters> q = default(Action<GetParameters)) { return null;}
