Add and remove tags from a server

[stefants]

Hello!

I'd like to add support to adding and removing tags from a VM. Please let me know if you have any questions!

Hi @stefants thanks for the PR... could you please point to the documentation where's this method? I tried to find and couldn't.

Thank you

Hi @fernandes ,

I'm not sure I follow... what changes on review?

I've also added some other methods to the VM class, but they're not related to this PR. If you prefer, I can surely open an issue to discuss them 😄

@stefants Sorry for missing this out.

Can i suggest one change?

If you take a look here you will find out that we are using meta programming to make some methods call out of the box.
When calling a method on an instance, if that instance does not have that method, it will automatically look for a request with that name appended with underscore and the object class name, in this case _vm.

This means that if you call this request add_tag_vm and remove_tag_vm it will be possible to call add_tag and remove_tag on a server object without even passing the reference like so:

@server.add_tag(tag)
@server.remove_tag(tag)

All current requests follow this pattern. See:
