ad223f2b50 fs: Use cache=none by default
The cache= option from the virtiofsd backend is meant to be used
depending on how the user wants to use the guest page cache. For most
use cases, we want to bypass the guest page cache to reduce the guest
memory footprint, which is why "cache=none" should be the default.

"cache=always" is the other option when the user wants to do something
specific by using the guest page cache, but should not be the default
anymore.

c81e808e98 docs: Update instructions regarding virtiofsd
The documentation was out of date since the URL to download virtiofsd
binary was not valid anymore. Instead, the updated documentation now
describe how to build virtiofsd from source.

Fixes #491

8ec89bc884 misc: Update to new repository locations
Update all references to the new repository locations. Many of these will
redirect however the one used for the hypervisor-fw binary does not so
this is required to allow the builds to pass.

d9695a0fd9 docs: fs: Update virtio-fs documentation
The cloud-hypervisor supports the DAX shared region for better virtio-fs
performances, but it was not updated in the documentation. This commit
takes care of this and also update the mount command since it changed
with virtio-fs v0.3.

Fixes #433

4b8d7e718d vmm: Add iommu=on|off option for --disk
Having the virtual IOMMU created with --iommu is one thing, but we also
need a way to decide if a virtio-blk device should be attached to this
virtual IOMMU or not. That's why we introduce an extra option "iommu"
with the value "on" or "off". By default, the device is not attached,
which means "iommu=off".

One side effect of this new option is that we had to introduce a new
option for the disk path, simply called "path=".
