Create vPool wizard times out on ALBA backend fetching

[wimpers]

In case you have many backends, the create vPool wiward will not load the ALBA backend due to a timeout.

we load all information about all possible backends, which times out in this case can be optimized by only loading the required information, being the name and preset information

[kvanhijf]

vPool wizard has been updated to only load the relevant ALBA backend data. Still, loading the 'presets' information can take quite some time and perhaps we should finetune this in another ticket

Steps

• Installed a 3 node setup
• Added 25 backends (preset 1,1,1,1)
• Initialized 50 disks
• Claimed 2 for each backend
• Initialized vPool wizard and looked at the networking happening

Output

Got all backend information necessary

Test result

The wizard does not timeout any longer but it is still not optimized. See: https://github.com/openvstorage/framework/issues/837 Closing.
