Package pkg renamed into internal vol.2

[piotrkowalczuk]

New attempt to move files located in pkg directory into internal. A completely fresh start as it was quite impossible to rebase the branch after so many changes. Plus I don't have permission to origin anymore.

I encountered an issue:

internal/admission/webhook.go:49:2: unknown import path "github.com/travelaudience/aerospike-operator/internal/client/clientset/versioned": cannot find module providing package github.com/travelaudience/aerospike-operator/internal/clien

I'm not able to find github.com/travelaudience/aerospike-operator/pkg/client package on master.

It is related to #1.

@piotrkowalczuk you have to run make gen.

[piotrkowalczuk]

Done. A few tests are failing, the same that fails on the master.

@pires do you consider any package from internal (originally pkg) directory to be for public use only?

I have to be honest with you and while looking at these changes I'm asking myself if whatever gains justify the effort and risk they carry. I wanted to be inclusive and take in mind any contributions, and I know you've tried to contribute long time ago, but I'm a bit anxious 😅

@pires Up to you man ;)
