Tony Breeds fe128f0672 Use modern PBR and hacking packages
The 2.0.0 is breaking in that it removes the use of warnerrors in
build_sphinux.

YAQL isn't using that feature, so it shoudln't break.

The cap on pbr is preventing other OpenStack projects that would like to
use pbr 2.0.0 (and sphinx 1.5.1) from doing so as it breaks
co-installability with yaql

Also hacking <0.11 had a similar issue so use a newer version of that also

YAQL: Yet Another Query Language

YAQL (Yet Another Query Language) is an embeddable and extensible query language, that allows performing complex queries against arbitrary objects. It has a vast and comprehensive standard library of frequently used querying functions and can be extend even further with user-specified functions. YAQL is written in python and is distributed via PyPI.

Quickstart

Install the latest version of yaql:

pip install yaql>=1.0.0

Run yaql REPL:

yaql

Load a json file:

yaql> @load my_file.json

Check it loaded to current context, i.e. `$`:

yaql> $

Run some queries:

yaql> $.customers
...
yaql> $.customers.orders
...
yaql> $.customers.where($.age > 18)
...
yaql> $.customers.groupBy($.sex)
...
yaql> $.customers.where($.orders.len() >= 1 or name = "John")
