From aa1503d8cec501c2c3ed0357a9ed8ca0ad12f2cf Mon Sep 17 00:00:00 2001

Subject: [PATCH] Auto-fix yaml rules

In order to reduce divergance with ansible-lint rules, we apply
auto-fixing of violations.

In current patch we replace all kind of truthy variables with
`true` or `false` values to align with recommendations along with
alignment of used quotes.
