This patch set updated two wrong words:
+ In error.py file, it should be changed from "messsage" to "message"
+ In utils.py file, it should be changed from "containg" to "contaning"

Shell script to create config drive being replaced with python
code in ironic-lib.

In Python 2.6 it was required to use {0}, {1}...{n} when using the
string format function. In Python 2.7 and Python 3 it it not required.

Change {N} to {} in code.

This brings the code in style alignment with other projects like
ironic and ironic-lib.

Binding to the first interface that has an IP address is error-prone: there is
no guarantee that ironic can reach us via this inteface. It is much safer to
detect the interface facing ironic and bind to it.

Unused LookupAgentInterfaceError exception is deleted.

The TinyIPA build also requires iptables dependency at build time to insert the
required kernel modules.

It's normal that ironic returns 409 Conflict from time to time, so
it's a bit confusing that we report this with Exception level and
traceback.

The iSCSI extension now tries to use Linux-IO first (via rtslib)
and falls back to tgtd if Linux-IO can't be used (e.g. in the CoreOS-based
image which uses containers).

The ISCSIError class defines a class-level message attribute with
value: "Error starting iSCSI target". This attribute is further
processed in RESTError.__init__ method, the ISCSIError super-class, to
create an Exception message concatenating self.message with provided
details argument.  However, the ISCISError.__init__ method provides a
details attribute prefixed with the same text to the super(ISCSIError,
self).__init__ method.  As a result, the text appears twice:
"ISCSIError: Error starting iSCSI target: Error starting iSCSI target:
ISCSI daemon didn't initialize. Failed with exit code 107. stdout: .
stderr: tgtadm: failed to send request hdr to tgt daemon, Transport
endpoint is not connected"

The patch purpose is to remove the details prefix to avoid duplicate
text in the exception text while honouring ISCSIError.message.

If an image cannot be downloaded for some reason, it is helpful for
operators to have the image path, checksum, and calculated checksums
available easily from the API.

Adds a new module ironic_python_agent.inspector and new entry point
for extensions, which will allow vendor-specific inspection.

Inspection is run on service start up just before the lookup.
Due to this early start, and due to the fact we don't even know
MAC address of nodes on inspection (to say nothing about IP addresses),
exception handling is a bit different from other agent features:
we try hard not to error out until we send at least something to inspector.

Exception messages weren't being bubbled up to the API because the
base exception class wasn't printing correctly. This adds a string
and representation function to ensure they print properly and show
up correctly when debugging interactively.

Cleaned up the `message` attr on the exception classes. It looks
like they started out all without a period, but started adding them
later. Changed classes that were setting error `details` == `message`
to use the default details provided in RESTError.
