Storage names on SRC can't have capital letters

If you create drives with capital letters, and enter those drive names on the workspace creator with caps you get the following situation:
```
bschilpero@localhost:/$ ls /data/
datasets storageRolfeWaterCycle2_3_1DevCache storagerolfewatercycle2_3_1devcache
shared storageRolfeWaterCycle2_3_1DevHome storagerolfewatercycle2_3_1devhome
```

Where the lowercase drives are the storage items that are mounted to the machine, and the drives with capital letters are the paths that the Ansible script expected the drives to be.

I guess this changed in the SRC backend @sverhoeven ?
