Cleanup odo cluster configure scripts

[mohammedzee1000]

Cleanup odo configure cluster scripts to make them more manageable.

• Move auth configuration into a lib (and update scripts accordingly)
• Relocate setup-operators script and update scripts accordingly
• Move Kubeadmin login to a seperate script
• Move platform-specific stuff into its on scripts (done as much as I could, moving to its own task)
• Merge configure-installer scripts into single script

The above PR is the first phase of the cleanup

I am working on the 2nd phase of this issue. The 3rd part, which is platform-specific stuff, I am expecting the alt arch teams to handle it.
