🐛 (eks sync-core-components): Increase maxEKSBuild, do binary search

[ThisGuyCodes]

Description

Fixes #214
Replaces #215

The maximum number of builds (sub-patches?) to search for with eks compnent images was hard coded to 10 (actually 9, since the last one has to error / miss for the code to work), but there are in fact 10 builds of eks/coredns:1.9.3-eksbuild. This massively jumps the threshold to 128, and switches to doing a binary search rather than a forward crawl to keep the request count down.

At present any attempt to create / update an EKS cluster using version 1.24 through 1.26 will error (see #214).

Release Notes

Find eksbuild's via binary search, Fixes #214

[ThisGuyCodes]

I feel this is a more permanent solution than #215, and it makes performance more consistent across the board. But I acknowledge it's much more complex so I'll leave it to the maintainers to decide.

Hi @ThisGuyCodes , we are testing this PR now. Can you confirm what version of kubergrunt you are using just for an apples to apples comparison? We'll take a look at both PR's that were opened, but might go with #215 initially. Will follow up either way.

I'm using the latest release, v0.13.0

[ryehowell]

Hi @ThisGuyCodes, we got #215 merged and released. v0.13.1 addresses the issue (I just verified). Thanks again for the contribution!

We can keep this PR open if you would like. I plan to circle back to function to update to a more robust solution that is less constrained with the limits and the overall implementation.

Happy to keep it open!
