What happened:

My Chart.yaml includes the following element:

[...]
type: application
[...]

which is a valid element according to the Helm docs.

Though, ct lint fails with

Validating /path/to/my/chart/Chart.yaml...
Validation failed!
Error validating data '/path/to/my/chart/Chart.yaml' with schema '/usr/local/etc/ct/chart_schema.yaml'
        type: Unexpected element

What you expected to happen:

ct should not fail validating Chart.yaml as type is a valid field.

How to reproduce it (as minimally and precisely as possible):

Add type: application to Chart.yaml and run ct lint.

Duplicate of #251 and already fixed in master.
