aql: add more examples, and add support to debug, such as printing built query string

[LeiYangGH]

when trying aql, with include, sort, and limit, I wasted a lot of efforts guessing what python equivalent syntax would be given the raw aql string.

I always got below error until I went over some issues and came up with the right solution:

requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: myhost/artifactory/api/search/aql

The error message is too general.

Could it be more acurate? such as some debugging functions to print the generated raw aql string?
And could any one add some example in readme? (if you allow, i'd like to add one example).

May be enable debug logging for requests could help you for the moment? https://gist.github.com/Daenyth/b57f8522b388e66fcf3b

if you allow, i'd like to add one example

We have some examples in documentation with include, but it can don't cover enough https://devopshq.github.io/artifactory/#artifactory-query-language

Of course, feel free to contribute documentation and code!
