Subject: [PATCH 1/2] Remove VxFlex OS credentials from connection_properties

VxFlex OS password is not stored in block_device_mapping table. Instead of this
passwords are stored in separate file and are retrieved during each attach/detach
operation.

Closes-Bug: 1823200
Change-Id: I10a8aaddbf7dd09830cd4189cd1f99c0ad1f3b60
