[CLOUDSTACK-9423] Add ability to get virtual size of compressed VHDs
With object store like Swift as secondary storage, if a compressed VHD is
uploaded as a template, the `VHDProcessor` incorrectly calculates the virutal
size leading to the template being useless. This fix tries to guess the virtual
size by partially decompressing it and falls back to a sensible default which
is the size of the file.
Before the fix: template.properties on Swift
```
uniquename=routing-1
filename=routing-1.vhd
size=263417314
virtualsize=2894447637315205059
```
After the fix
```
uniquename=routing-1
filename=routing-1.vhd
size=263417314
virtualsize=3145728000
```
Look at the `virutalsize` in both cases
