get_bucket_region does not work for buckets with periods in them

[aditya-nambiar]

Describe the bug

If you use a bucket with period in it, you get the error -

2: error sending request for url (<bucket_url>): error trying to connect: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed:ssl/statem/statem_clnt.c:1919: (Hostname mismatch)
3: error trying to connect: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed:ssl/statem/statem_clnt.c:1919: (Hostname mismatch)
4: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed:ssl/statem/statem_clnt.c:1919: (Hostname mismatch)
5: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed:ssl/statem/statem_clnt.c:1919:

this is because the bucket has periods.

To Reproduce

Expected behavior
It should also work for buckets with periods
