Fix unconventional labels and selectors

[krancour]

There are numerous places in the chart's many manifests where labels and selectors such as name: foo have been used instead of the more conventional app: foo. This should be corrected.

+1. I've checked in a few offending manifests

[krancour]

I'm going to fix these when I get a minute. @technosophos should these be fixed only in the dev charts? i.e. should we treat the "released" / alpha charts as immutable until we refresh them to reflect the beta release? I think we should update the alpha charts in this particular case since doing so won't affect functionality.

[arschles]

@krancour see #41 for a start on changing the labels

RE your released/alpha question - I agree that we should update alpha charts here

[krancour]

Uh. I am a dummy. I totally scrolled right past the cross-reference to #41 above and didn't notice it. Can you merge #41 (it has its LGTMs) and I will go after any stragglers after that?

[krancour]

Although there probably aren't any stragglers after this. Just reassigning this to you. Thanks.

@krancour judging by comments, I'm the only one to have tested it and I think it'd be good to have others test as well before merge. I'll continue the conversation on the PR
