AzureGraph 1.1.1

AzureGraph 1.1.0

Updated to use the new Graph API calls for managing app passwords. Call the az_app$add_password() method to add a password to an app, and az_app$remove_password() to remove it. As a security measure, app passwords can no longer be manually specified; instead all passwords are now auto-generated on the server with a cryptographically secure PRNG.
- The az_app$update_password() method is defunct.
Better handling of app creation with certificates:
- The certificate argument to ms_graph$create_app() can be the name of a .pfx or .pem file, an openssl::cert object, an AzureKeyVault::stored_cert object, or a raw or character vector containing the certificate.
- New az_app$add_certificate() and az_app$remove_certificate() methods, matching add_password and remove_password.
Treat the access token as opaque; this prevents errors when logging in without an AAD tenant.

Fix a bug in user methods for listing objects when the result is empty.
Fix a bug in retrieving users added to an Azure Active Directory (AAD) tenant from an external directory.

Allow AAD v2.0 tokens to be used for authenticating. Note that AAD v1.0 is still the default and recommended version.
Use utils::askYesNo for confirmation prompts on R >= 3.5, eg when deleting objects; this fixes a bug in reading the input. As a side-effect, Windows users who are using RGUI.exe will see a popup dialog box instead of a message in the terminal.
Various other bug fixes.

Changes to login functionality to better accommodate AzureAuth options. As part of this, the config_file argument for az_graph$new has been removed; to use a configuration file, call the (recommended) create_graph_login function.
