[BUG] An app cannot contain different types of files

[YTGhost]

What happen?

I have written a Kubefile containing the nginx app, which contains a yaml file and a shell file. When executing sealer build, the build reports an error.

[ERROR] [root.go:75] sealer-v0.9.1: failed to judge the application type for nginx: mixed app type is not supportted

Relevant log output?
