Make YAML parser a bit less strict for booleans and numbers

Short description

Allow quoted values in YAML for booleans and numbers

Usecase

Ansible produces quoted values in some cases, while our YAML parser is strict with respect to types: "true" or "123" is not accepted where a boolean or number is expected, respectively.

Description

Accept quoted values for booleans and numbers.

I looked briefly into serde_yaml, but found no easy way to do this. It might be needed to modify serde_yaml....

Note: it would be much more preferable to modify the Ansible stuff to generate properly typed YAML files. Only if that is not feasible this feature request becomes relevant.
