This API is used to add tags to a BMS.

You are required to use the HTTP header X-OpenStack-Nova-API-Version: 2.26 to specify the micro version on the client.

A BMS can have a maximum of 50 tags.

It is recommended that you add the __type_baremetal tag to BMSs to distinguish BMSs from ECSs. Otherwise, BMSs will be available only on the ECS console.
A new tag will overwrite the existing one. If you want to retain the original tag, add it to the list of new tags. You are advised to add __type_baremetal to the added tags list each time you add a tag.
