Description of problem (please be detailed as possible and provide log
snippests):
Two problems where found on validation "Edit Block Pool label" 

1. When passing consequent dots (..) no warnings appear. https://drive.google.com/file/d/1TOhZ3NCHegLR4QMoBmYCL91a-kWggLty/view?usp=sharing

2. When passing invalid label name and have warning message you still can click on save https://drive.google.com/file/d/1PHsTXYkK5fSOb7KVpnhU4BHlOVDWAf1S/view?usp=sharing. User gets wrong impression that label was saved.
But when user passing invalid label that violates rule, that first or last symbol should be alphanumeric - user can not save such label. We need to make straight behavior on invalid label. From UX point the popup should not allow to save such label and close the Edit label popup when clicking Save.
