.`cephadm` no longer attempts to parse the provided yaml files more than necessary Previously, `cephadm` bootstrap would attempt to manually parse the provided yaml files more than necessary. Due to this, sometimes, even if the user had provided a valid yaml file to `cephadm` bootstrap, the manual parsing would fail, depending on the individual specification, causing the entire specification to be discarded. With this fix, `cephadm` no longer attempts to parse the yaml more than necessary. The host specification is searched only for the purpose of spreading SSH keys. Otherwise, the specification is just passed up to the manager module. The `cephadm bootstrap --apply-spec` command now works as expected with any valid specification.
