disk: attach disks with serial number at controller

[huww98]

What type of PR is this?

/kind cleanup

What this PR does / why we need it:

Attach and detach must be migrated at once, because NodeUnstageVolume may be followed immediately by anoterh NodeStageVolume, without controller actions.
So if we detach disk at NodeUnstageVolume, NodeStageVolume will not find the disk.

Note: user must upgrade controller before node, to avoid any missing detach.

This is the first step to move all attach/detach back to controller, in order to:

• reduce RAM permission on node
• more effective request batching
• rely less on node, which can be down
• resolve some rare racing issue

Which issue(s) this PR fixes:
