Merge pull request #1598 from syed/vhd-compressed-size
[CLOUDSTACK-9423] Add ability to get virtual size of compressed VHDsWith 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

> When uploading templates to an object store like Swift, if the template is
> compressed, we get an invalid size (negative). This fix tries to see if the
> template is compressed, if so, gets the correct size by partially
> decompressing the VHD header.
