various fixes for fiberchannel and autoscale prefix option

[rg9975]

Description

This PR fixes various issues in the fiberchannel/adaptive storage provider, including adding an optional interface for handling connecting disks in a 3 step process to improve performance on VMs with a large number of disks to connect. One additional change is included to provide an option to disable the fixed string prefix added to autoscale VMs to allow for longer generated names. A couple of small annotations were added to help builds when running in an m2e-compatible IDE.
