Expose Query Parameters

Here is the proposed API changes to make it where user can access the query parameters. This is a follow up to PR https://github.com/Azure/azure-cosmos-dotnet-v3/pull/802#issuecomment-773663109

Option 1: public IEnumerable<(string key, object value)> GetQueryParamters();

Option2: public IReadOnlyList<(string key, object value)> GetQueryParamters();

Option 3: Does it give a snapshot or a mapping to the underlying data structure? public IReadOnlyDictionary<string, object> GetQueryParamters();

@thomaslevesque, @FabianMeiswinkel, and @kirankumarkolli what are you opinions?

@j82w That works for me. I’ll send a new PR, the original one is too messed up now…
