1. Support virtual hosting endpoint.
2. On-premise s3 compatible storage service may use IP instead of s3 form domain name,
especially for development/test environment.
Instead of parsing service and region from domain name,
1). Hard code "s3" as service name in v4 signature
2). Add new parameter to allow pass region name from url
3. Fix creating bucket issue on aws, adding request body.
1. For v4 signature, http request path should be encoded, currently only parameters are encoded.
2. For v2 signature, http request date header should be in form of either the http date header or x-amz-date, currently in form of ISO 8601
3. Empty response header value cause http_bad_response error.
4. Skip verifying MD5 for range get request and if http response code 206 is returned.

* Move ClientKnob::COORDINATOR_HOSTNAME_RESOLVE_DELAY to FlowKnob::HOSTNAME_RESOLVE_DELAY.
* Move Hostname to its own files.
Also, add resolve-related variables and functions in Hostname.
