Artom Lifshitz e80e2511cf Fix tag attribute disappearing in 2.33 and 2.37
In the context of device tagging, bugs have caused the tag attribute
to disappear starting with version 2.33 for block_devices and starting
with version 2.37 for network interfaces. In other words, block
devices could only be tagged in 2.32 and network interfaces between
2.32 and 2.36 inclusively.

This patch documents this behaviour in api-ref and introduces
microversion 2.42, which re-adds the tag in all the right places.

In the context of virtual device role tagging at server create time, the
2.42 microversion restores the tag attribute to networks and
block_device_mapping_v2. A bug has caused the tag attribute to no longer be
accepted starting with version 2.33 for block_device_mapping_v2 and
starting with version 2.37 for networks. In other words, block devices
could only be tagged in version 2.32 and network interfaces between
versions 2.32 and 2.36 inclusively. Starting with 2.42, both network
interfaces and block devices can be tagged again.
