Add default function from chart template to check release name match

[timm088]

What this PR does / why we need it:

When releasing these charts, service name will be prefixed with the release name, resulting in name-name. This also impacts DNS resolutions.

Special notes for your reviewer:

From my research, looks like the default chart template was changed (i.e., when running helm create locally), this function was just not added here.

Hi @timm088. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

I understand the commands that are listed here.

Please create separate PRs per chart. Thanks.

Will do. Looks like the chart has been updated in the last < 1w for the consul chart also.
Will close this PR and then open again as seperate PRs
