More flexibility around creating/updating tags

[magixus]

Describe the bug
At the moment, when trying to add/update tags it's a bit complicated, you have to set a comma separated list of tags, if you wanna update, it's not adding your existing tags to the list. (you have to rewrite them)

To Reproduce
Steps to reproduce the behavior:

1. Go to devices
2. Checkbox a device that contains tags
3. Try to Update

Expected behavior
We should be able to have a little bit of flexibility when updating tags, like be able to find same tags and be able to update them. (remove, add)

Example:

I'm not sure I agree with this change. If you are to select three devices, which tags should be prepopulated?

I think the UI you showed is lovely, and we should add it, but I don't think the set tag(s) to should have tags automatically added to it.

@joshk good point, you're correct. IMO this UI should be implemented on the device settings page.

[magixus]

good point @joshk.
I was thinking about it before writing this issue, and I hoped you guys will make improvements to the UI and keep bulk tags updates as it is.

Here's my suggestion:
if one device is selected => copy same tag with enhanced UI
if multiple selection => keep tags empty.

What about a way to add tags instead of setting them ? Imagine having 10 or 100 devices with a set of tags (there's a unique tag per device), and you want to add a common tag, in this case, you need to add the tag to the devices one by one otherwise you risk resetting all of them.

@magixus I think this suggested behaviour would be a little confusing for people. Seeing the tags list populate and then become empty would be confusing; at least, it would be for me. Feature behaviour should be consistent, and this would break that rule.

@gBillal This is an interesting request. Could you please split it out into another issue for discussion?
