Credential Chain for Seamless 'OAuth 2.0' Authentication to
'Azure Services'
Description
Implements a credential chain for 'Azure OAuth 2.0' authentication
based on the package 'httr2''s 'OAuth' framework. Sequentially attempts authentication
methods until one succeeds. During development allows interactive
browser-based flows ('Device Code' and 'Auth Code' flows) and non-interactive
flow ('Client Secret') in batch mode.
