dvc metrics show - implement jsonpath-ng instead of python-jsonpath-rw

[brbarkley]

Hello,

For passing JSONPath to dvc metrics show is it possible to use jsonpath-ng under the hood instead of python-jsonpath-rw?

jsonpath-ng seems to more fully support JSONPath features, for example the ability to filter on certain values: $..book[?(@.price<10)] which would be useful for comparing metrics with greater specificity from dvc metrics files.

Thanks for considering!

Hi @brbarkley !

Great question! I don't quite remember why we've opted for python-jsonpath-rw. Looks like we could simply start using jsonpath-ng instead and we should be fine as long as tests pass. Would you like to submit a PR? 🙂

Thanks,
Ruslan
