Update (un)deploy helm plugins
- Added support for deploying and undeploying individual releases. - Added support for a --verbose flag to output details during a deploy. By default, verbose output will be supressed. - Fixed issues preventng some flags from propagating to helm commands. - Fixed issue where by --set <chartname>.enabled=false was not removing disabled Helm Charts.
