Enh/update eks module

[mglotov]

PR Description

• Updated eks terraform module to the latest possible version (the version without any political slogans).
• Changed a way of updating/patching aws-auth configmap. Terraform module documentation uses local-exec, but this approach isn't very useful. I've decided to use kubectl provider to update aws-auth configmap and to get rid of running locac-exec.

Fixes #244
