Velero should handle cases when the label length exceeds 63 characters. - if the length of the backup/restore name is <= 63 characters, use it as the value of the label - if it's > 63 characters, take the SHA256 hash of the name. the value of the label will be the first 57 characters of the backup/restore name plus the first six characters of the SHA256 hash.
