feat: add api to enableVirtualStyleEndpoint

[warjiang]

New to use aliyun oss. With ak\sk\endpoint, the aliyun oss server always response with error: SecondLevelDomainForbidden。I need to add api to support virtual_style_endpoint like minio python sdk.

if without this api, developer must specify pathStyle=false when init minio client, and this api is ambiguous.

with this api, it's will be clear for developer

@prakashsvmx
as mentioned in #854 , it's not a good way to list all cloud storage provider such as amazon or aliyun, expose virtual path style setting to developer takes more compatibility as more and more cloud storage provider enable virutal path style.
