Fixing bugs related to nested blocks inside roles
* Make sure dep chains are checked recursively for nested blocks * Fixing iterator is_failed() check to make sure we're not in a rescue block before returning True * Use is_failed() to test whether a host should be added to the TQM failed_hosts list * Use is_failed() when compiling the list of hosts left to iterate over in both the linear and free strategies Fixes #14222
