CreateBucket: dot character is not properly parsed in bucket names

[evgeniiz321]

Due to https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucketnamingrules.html:

Bucket names can consist only of lowercase letters, numbers, dots (.), and hyphens (-).

test_bucket_create_naming_good_contains_period currently fails with:

2023-11-09T04:26:17.194Z	error	handler/util.go:29	call method	{"status": 500, "request_id": "2a51845f-8d45-48fd-b997-24f5a4efc113", "method": "CreateBucket", "bucket": "yournamehere-jzqvzsxa3jf0if1f-aaa.111", "object": "", "description": "could not create bucket", "error": "create container: save container via connection pool: put: status: code = 1024 message = chain/client: contract execution finished with state FAULT; exception: at instruction 1050 (THROW): unhandled exception: \"invalid domain name format\""}

Seems like when '.' is specified, a part of a bucket name is interpreted as a domain name

Wow. That's an interesting one. We really use NNS to store container names and dot obviously creates a subdomain.
