Remove installer/uninstaller in favor of kubectl apply

[jessesuen]

Is this a BUG REPORT or FEATURE REQUEST?: FEATURE REQUEST

What happened:

The argo installer/uninstaller is not totally useful for the following reasons:

• we will never accommodate everyone's desired installations. For example, customizing argo to have resource quotas is not possible via instalelr.
• the installer does not benefit from kubectl apply semantics since it uses REST update instead of patch.
• the uninstaller is too easy to shoot yourself in the foot by blowing away the CRD (and all workflows in the cluster).

This proposal is to remove the argo install and argo uninstall commands completely, and direct users to running kubectl apply to install argo instead.

@jessesuen I have written some helm charts for this that kinda provide a very easy way to configure and install argo. I am happy to adapt that for a more generic way.

Thanks for offering @andreimc, looks like we are just now getting some help on the Argo Helm front (See: argoproj/argo-helm#14). Feel free to chime in there if you have any suggestions for improvements.

As for this issue, argo install and argo uninstall have now been removed so closing out this bug.
