PTFE-742 cannot store redhat password as secretstr

[tcarmet]

var of type SecretStr are being stored as ***** in redis with redis-om. Leaving us unable to retrieve the proper password when the group is retrieved from the database and not from the settings configuration in the code.

Now defining the var as str until we find a proper solution to the issue.
