Also displays any config_info credential object with 'credential' in the key

This work follows the following assumptions:

1. dialog objet will always over config info - for provision does not exist in reirement
2. dialog_credientail will always override credential_id
3. from the dialog object, to the config_info - dialog_cloud_credential -> (normalized) cloud_credential - will override cloud_credential
4. when avaliable, all possible credential types will have "credentail" in the object key, and be contained in config info (if not overridden)

@AllenBW let me know if you want me to review. Happy to help!

[bzwei]

To include other credential type, should it be something like

  return normalizedKey.contains('credential') ? normalizedKey+'_id' : normalizedKey

[AllenBW]

@bzwei if at dialog has a credential override of dialog_cloud_credential_id the change you are proposing would result in a normalized key of cloud_credential_id_id

This conditional is to catch the edge case of dialog_credential which would be normalized to credential which would not override the desired machine credential which is called credential_id

[bzwei]

per our discussion, we wanted a generic solution for future dialog overriding credentials.
I am OK (and good to play it safely) if we just do the correction for credential alone here, and add more corrections in the future if other other credential types can be overridden. (currently only (machine) credential can be overridden)
Since you only need to look for one and only credential, you do not need to use a map.

unclear watcha mean by this ☝️ 😕

[bzwei]

I thought you use a map from credential to value. In this map it can be only one pair. why bother?

[AllenBW]

In the case of provision and dialog present, we map through each dialog keys, normalize them and assign them to the config_info object. Without this we miss all overrides 😬

[AllenBW]

@kedark3 was gracious enough to make a machine, looks like we're lookin' gooooood!!!

🌮 💃
