[PengLingJun]

we are use alicloud kms to auto unseal.so,we are have some ak/sk env in vault starup script.

but,if i use alicloud secret engine. alicloud/config ak/sk config not working.

I review some code for that plugin:

that define first find env config.that not great,in secret engine case,not need read env config,that ak/sk will defined in alicloud/config
