Fix: Use status endpoint instead of config endpoint for service account resource APIs

[noredistribution]

Fixes #234

Change svc_account_get_one and svc_account_get_all to use the status endpoints instead of the config endpoints

AccountService/GetOne and AccountService/GetAll instead of AccountConfigeService/GetOne and AccountConfigService/GetAll

this will gain us two extra key values:

• created_by: the user that created the service account
• last_access: the last time the service account accessed the system

this change should be transparent for users who've used these functions before as the return data has the same format + those 2 k,v pairs

• added system test as well to check for those 2 new keys
