detect-helm and multiple uses of the same chart

[lucasreed]

When multiple releases are from the same chart, I think we should only show one instance of that output.

for example, if helm ls shows this:

NAME                                        	REVISION	UPDATED                 	STATUS  	CHART                              	APP VERSION	NAMESPACE
app-develop                                 	5       	Tue Apr 21 04:13:25 2020	DEPLOYED	app-1                           	1.0        	develop
app-qa                                       	5        	Tue Apr 21 04:13:25 2020	DEPLOYED	app-1                           	1.0        	qa

We should only output a single line for any deprecations found in that chart. This may be easier if we end up pulling in chart name data with #31

[lucasreed]

We decided limiting this output would be a disservice to the user. We should report all deprecation/removal(s) we find even if the chart name + version match. Not everyone iterates on their chart version number (for SHAME!) so we could potentially hide issues if we only print out a problem with a chart and not every release of the chart.
