Maybe fsspec can't working well in Azure CN

[MrKassadin]

I found that whe the Protocol is abfs[s]
In this source file:adlfs/spec.py
STORE_SUFFIX = ".dfs.core.windows.net"
It should working well in Azure,
But in Azure CN,it should be STORE_SUFFIX = "dfs.core.chinacloudapi.cn"
And other like f"https://{self.account_name}.blob.core.windows.net"
in Azure CN should be f"https://{self.account_name}.blob.core.chinacloudapi.cn"
Or here:
r"(?P<account_name>.+).(dfs|blob).core.windows.net", host
in Azure CN should be r"(?P<account_name>.+).(dfs|blob).core.chinacloudapi.cn", host

Hi @MrKassadin in order to connect to an AZURE CN endpoint, have you tried setting the account_host parameter? e.g.,

fs = AzureBlobFileSystem(
    account_host="myaccount.blob.core.chinacloudapi.cn",
    account_name="myaccount",
)
with fs.open("container/blob.txt") as f:
   print(f.read())

Let us know if that works for your use case and unblocks you.
