Add config file support
...
Support yaml/json based config file for nfd. This commit does not add
any actual consumers for the config file, yet.
By default, nfd tries to read
/etc/kubernetes/node-feature-discovery/node-feature-discovery.conf.
This can be changed by specifying the --config command line flag.

Implement detection of IOMMU ( #136 ) ( #137 )
...
* Arrange feature sources alphabetically
Just a cosmetic change, but, a small readability improvement.
* Implement detection of IOMMU (#136 )
Add a new feature source, i.e. 'iommu', which detects if an IOMMU is
present and enabled in the kernel. The new node label is
node.alpha.kubernetes-incubator.io/nfd-iommu-present

Advertise selinux status by adding labels
...
This commit:
- enables node-feature-dicovery to advertise selinux status
on the node by adding a label.
- update the template to mount /sys into the container, this is
needed to know about the selinux status on the host
- adds selinux source for unit tests

Add memory source and NUMA detection.
...
If multiple nodes are marked online in
/sys/devices/system/node/online, it's a sign of NUMA
architecture. Mark it using nfd-memory-numa label.

Added nonrotational storage detection
...
This change adds feature source "storage".
Add label if any non-rotational block device is present in the node.
The label will be: nfd-storage-nonrotationaldisk=true

Fixes #25 : Deletes non-discovered nfd labels
...
Adds RemoveLabels() to remove all labels from a node that contains the
supplied search string. Uses this to remove node-feature-discovery
labels prior to re-applying newly discovered labels.
This behavior applies to consecutive runs of node-feature-discovery and
whatever restrictions are placed on it. For example if a whitelist is
specified that changes the labels that are discovered, any labels that
do not match the whitelist will be removed. Adds a small note to the
readme to point out this fact.
Adds tests to main_test.go to test the behavior of AddLabels and
RemoveLabels.
