Configmap incorrectly loading break lines

[gianrubio]

The PR #373 introduces an issue when ingress is loading configmap, with break lines. It loads a broken configmap, avoiding nginx start.

Nginx error

Error: exit status 1

Also my log_format is broken, I setup on configmap without $proxy_protocol_addr. I already make some comment on #373 (comment)

@gianrubio please remove the ' character at the beginning and end.
