Add eksctl support to AWS plugin

[skpaz]

Overview

Adds rudimentary eksctl support to the AWS plugin. eksctl uses the same authentication schema as aws and cdk, so all I did was add eksctl.go, the related executable to plugin.go, and tested it locally.

https://eksctl.io/

eksctl is maintained by Amazon.

Type of change

• Created a new plugin

How To Test

Any eksctl command, ex:

14:34:30 › ~/git/skpaz/shell-plugins »
∟ ⌥ skpaz/add-eksctl-to-aws ↑ % eksctl get clusters --region us-west-2
###########################################################################
# WARNING: 'aws' is not from the official registry.                       #
# Only proceed if you are the developer of 'aws'.                         #
# Otherwise, delete the file at /Users/sean/.config/op/plugins/local/aws. #
###########################################################################
NAME			REGION		EKSCTL CREATED
KKR-BORIS		us-west-2	False
basic-cluster-kkr-01	us-west-2	True
john-test-cluster	us-west-2	True
johnl-gex-fullstack	us-west-2	True
vw-kkr-demo01		us-west-2	False

Local plugin:

15:27:09 › ~/git/skpaz/shell-plugins »
∟ ⌥ skpaz/add-eksctl-to-aws % op plugin list|grep -i aws
Local Build           aws                AWS                   Access Key ID, Secret Access Key
Local Build           cdk                AWS                   Access Key ID, Secret Access Key
Local Build           eksctl             AWS                   Access Key ID, Secret Access Key

I haven't tested this exhaustively, so it's possible there might be flags other than --profile that need to be added to cli_provisioner.go, etc. I'll be running with it for the next week or so to see if I encounter any issues.

Changelog

The AWS plugin now supports eksctl, AWS' EKS CLI.
