@ershovaelena should we allow this tags?
I think this tags should be invalid. What do you think?

[elenaustyugova]

Discussed with PO: don't let create tags with spaces. Add validation when creating tag.

Need to clarify requirements

Discussed with PO:

The only restriction is no spaces as the first symbol in keys and values. Show error when entering space as the 1st symbol.

So user can enter numbers, spaces inside of keys and values, special symbols.

Error entering a space character in the "Value" field is not localized

Steps:

1. Go to VM/Image/Firewall tags of any entity
2. Go to create or edit tag
3. Enter space character in "value" field

Actual result: Error appears with a text "TAGS.TAG_INVALID"
Expected result: Error appears with a text "Field value must start with 'non-space' character"
