✨ (go/v4): Add method to allow users distribute the project

[camilamacedo86]

Description

• Add target to build the installer under dist/install.yaml
• Also, add e2e tests to ensure that installer will be working well as expected
• By last, add instruction into the README generate to make clear how to achieve this goal

Proposed Solution

Just generate the YAML with all that should be installed (same kustomize build of make install and make deploy) so that the project can be distributed as usually it is done by many solutions like Operator Prometheus for example, where users can run: kubectl apply -f dist/install.yaml and maintainers can easily project the raw of the file.

Motivation

• Is there a good solution/tool to generate a new helm chart from the manifests? #3074
• How are you distributing the projects built with Kubuilder? #3081

Closes: #3185

IMPORTANT: For we are able to check out the changes of this PR we must to have here the fix addressed in the PR: #3627 . So this one is blocked until we are able to merge the fix

HI @dashanji, @Kavinjsir , @Jay-Madden, @LCaparelli, @vbehar, @varshaprasad96 @everettraven

This one seems good to fly now.
Feel free to check.

Also, see that we are testing the installer with the e2e tests.

Looks good to me in general!
This is a great feature.
I just left some nit and one open question.

@camilamacedo86
Thanks for the great feature. I think it's a good point to build a bundled YAML for distributing the kubebuilder operator.
I just wonder what's the difference between kubectl apply -f https://raw.githubusercontent.com/<org>/project/<tag or branch>/dist/install.yaml and kubectl apply -k https://github/<org>/project/<tag or branch>/config/default?
The gain I can think of is that the common kubernetes users don't need to study the kustomize grammar and a bundled YAML is very straightforward.

Looks like unit tests a failing. Would have to dig deeper, probably import issues, or version bumps in ginko?

[camilamacedo86]

@varshaprasad96

The unit tests are failing for unrelated reason, it was fixed here: #3743 (coverage test bumped with go 1.19 instead of 1.20)
I closed and re-opened the PR to see if it will get master changes. If not, I just rebased, and we are done.

Really thank you for your help and support 🥇
