Display error message on template delete failure

If some error occurs when a template is deleted, no message is displayed
to the user.

Display an error message so the user knows something went wrong.

A new translation entry has been added: "Failed to delete template.".

distros: add a DistroLoader to load distros

The distro iso links will be stored in /etc/kimchi/distros.d/

A basic DistroLoader class that reads all of the files and produces
a python array identical to the osinfo array.

Adam Litke suggested:
The distros files cannot be updated at runtime.
The only thing kimchi needs to do with the files in /etc/kimchi/distros.d
is read them to create a large json list of template objects.
It will never write to those files.

user can create a file in /etc/kimchi/distros.d by installing / upgrading
a package

feature tests: Verify QEMU supports ISO streaming

From qemu source code, iso streaming is supported since version v0.11.0-rc1
But Kimchi needs to know if the qemu installled has this support in order
to enable/disable creation of ISO streamed templates.

feature tests: Verify QEMU can properly work with hostname while streaming ISOs

The ISO streaming functionality is not working well on Fedora 19.
With qemu-kvm-1.4.2-12 and curl-7.29.0-6 packages installed, it is
not able to create virtual machines with streamed ISOs when the
cdrom URL uses host name instead of IP address.
So create a sanity test in order to identify that case to properly
handle it on Kimchi.

iso streaming: Libvirt workaround

The ISO streaming support was recently added to libvirt so the most current

To allow the Kimchi user creates templates with streamed Internet ISO verify
if the libvirt has ISO streaming support and if not uses qemu/KVM directly
through <qemu:commandline> libvirt tag.
