Fixes#27366
A URL with numeric host part formats special in case of ipv6,
to avoid confusion with port part.
The parser should handle this.
I.e.
http://[2001:db8:4006:812::200e]:8080
v2:
* Include scheme agnostic parse + case insensitive scheme matching
Also allow creating the object using an endpoint expression.
Note: this moves code to the .cc file, because it introduces a few
more lines, and I feel we have to much stuff in headers as is.

Patch adding this somehow managed to leave out the thread_local
specifier. While gnutls cert object can be shared across shards
just fine, the actual shared_ptr here cannot, thus we could
cause memory errors.

Fixes#24447
This factory type, which is really more a data holder/connection producer
per connection instance, creates, if using https, a new certificate_credentials
on every instance. Which when used by S3 client is per client and
scheduling groups.
Which eventually means that we will do a set_system_trust + "cold" handshake
for every tls connection created this way.
This will cause both IO and cold/expensive certificate checking -> possible
stalls/wasted CPU. Since the credentials object in question is literally a
"just trust system", it could very well be shared across the shard.
This PR adds a thread local static cached credentials object and uses this
instead. Could consider moving this to seastar, but maybe this is too much.
