Feature request: Reduce use of lesser known packages in Idemopotency package

[mungojam]

Use case

We have to be careful with the dependencies that we bring in. The Idempotency package brings in a JmesPath package which then brings in other sub-packages. The sub-packages are particularly obscure, developed as a university project with very few users. https://www.nuget.org/packages/Springcomp.GPPG.Runtime

We would like the JmesPath package dependency to be replaced with native System.Text.Json functionality, or else a more widely used package (e.g. Newtonsoft.Json).

Otherwise I don't think we will be able to make use of the Idempotency package.

Solution/User Experience

It seems that the main use is here, and could be replaced with a System.Text.Json use:

@mungojam Thanks for raising this feature request. We are discussing what you wrote between the team and will get back to you soon.
I agree with you, the less dependencies we have the better, if we can achieve the same functionality with System.Text.Json seems like a good approach to me.

Hi @mungojam just to give you an update: PR created #578

[hjgraca]

@mungojam Release 1.10.0 removes dependency on 3rd party JMESPath. Using Idempotency 1.2.1 will not have that external dependency.
Hope you find it useful and reach out if you have any other questions or suggestions.
Thanks

@hjgraca nice one, thanks for the change. We'll look to adopt it now as nothing blocking anymore
