feat: support changing default port

[rtoma]

Fix for https://github.com/drone/charts/issues/12

[rtoma]

Unsure how to resolve failed check. Drone logs show: Error: Error linting charts: Error processing charts - not much to go on.

Try bumping up the version of chart-testing in the .drone.yml file. For example:

# git diff -- .drone.yml
diff --git a/.drone.yml b/.drone.yml
index fb06b93..047a8b0 100644
--- a/.drone.yml
+++ b/.drone.yml

The output is more informative in this version.

Apologies for the delay on this.

Changes have been pushed to master that should fix the build failure, can you rebase? Thanks
