This PR introduces a new Key Provider to support Azure Key Vault as a Key Management System (KMS) for Encryption at Rest. The core design principle is the same as in the AWS and GCP key providers - an externally provided Vault key that is used to protect local data encryption keys (a process known as "key wrapping"). In more detail, this patch series consists of: * Multiple Azure credential sources, offering a variety of authentication options (Service Principals, Managed Identities, environment variables, Azure CLI). * The Azure host - the Key Vault endpoint bridge. * The Azure Key Provider - the interface for the Azure host. * Unit tests using real Azure resources (credentials and Vault keys). * Log filtering logic to not expose sensitive data in the logs (plaintext keys, credentials, access tokens). This is part of the overall effort to support Azure deployments. Testing done: * Unit tests. * Manual test on an Azure VM with a Managed Identity. * Manual test with credentials from Azure CLI. * Manual test of `--azure-hosts` cmdline option. * Manual test of log filtering. Remaining items: - [x] Create necessary Azure resources for CI. - [x] Merge pipeline changes (https://github.com/scylladb/scylla-pkg/pull/5201). Closes https://github.com/scylladb/scylla-enterprise/issues/1077. New feature. No backport is needed.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
