lxd/kvm integration test failures due to changed metadata value

[Chad Smith]

Cosmic integration tests are failing on lxd and nocloud kvm platforms due to failed/invalid assertions.

v1_data (instance-data.json) changed cloud_name for nocloud kvm and lxd to report 'nocloud' instead of 'unknown' for the cloud_name key. Need to fix test assertions.

FAIL: test_instance_data_json_kvm (tests.cloud_tests.testcases.bugs.lp1628337.TestLP1628337)
Validate instance-data.json content by nocloud-kvm platform.

Marked invalid. This failure was due to cloud-init's integration tests filed LP: #1797189 to track integration test fixes.
