Fixes an issue when user forgot to combine
'kolla_ansible_custom_passwords',
'kolla_ansible_default_custom_passwords' and own dictionary with
custom passwords in configuration files. Now
'kolla_ansible_extra_custom_passwords' should provide only user
custom passwords to add or override in the passwords.yml.

Various functions in the development/testing scripts rely on 'kayobe
configuration dump' to extract the value of flags. If this command fails
for any reason, we should exit the script. Currently, some places we
continue and return 1, since we check the output against the string
'true'.

The to_bool helper function handles failure by checking for a valid
boolean output, so let's use that everywhere.
