No stdout output/feedback during long series of authenticator config update requests

[gim-]

Problem Statement

When applying a config with custom authentication flow, somewhere near the end keycloak-config-cli makes a series of silent requests to update authenticator configurations, even if they haven't changed. This can be seen in the Keycloak admin events:

{"authUsername":"admin","realmName":"REALM","resourcePath":"authentication/config/3b7931a9-0b0b-4419-b53a-b6bc8a73dc90","ipAddress":"172.18.0.1","operationType":"UPDATE","eventType":"ADMIN","resourceType":"AUTHENTICATOR_CONFIG"}

I assume due to Keycloak Admin API limitations there's no efficient way to check if config changed or not, so the tool is just overwriting everything just in case (correct me if I'm wrong). (since the tool is using realm export representation, can't it compare new config with old one to avoid redundant updates?)

But I'd expect some feedback when it does it instead of silence, as the delay is quite significant with a large number of configurations in a file.

Proposed Solution

Add some feedback to stdout when updating authenticator configs so it doesn't appear like the tool isn't doing anything.

Printing a separate log message for each request would probably be too much, so maybe it could print some progress every N number of seconds? E.g.

Updating authenticator configurations (0/300)
Updating authenticator configurations (50/300)
Updating authenticator configurations (110/300)
...
Updating authenticator configurations (300/300)

Environment
