use deep_merge overwrite_arrays option

[tongueroo]

This is a 🐞 bug fix.

• I've added tests (if it's a bug, feature or enhancement)
• I've adjusted the documentation (if it's a feature or enhancement)
• The test suite passes (run bundle exec rspec to verify this)

Summary

Fixes #45

Context

When specifying targetPort in a service.rb DSL definition, it adds to the ports array instead of overriding the existing one.

How to Test

$ cat .kubes/resources/web/service.rb 
name "web"
labels(role: "web")

# Optional since default port is 80
# port 80
targetPort 8080 # expose port in Dockerfile

# More docs: kubes.guru/docs/dsl/resources/service/
$ kubes compile ; cat .kubes/output/web/service.yaml
Compiled  .kubes/resources files to .kubes/output
