Raise an error if module import fails.

Previously a missing module would cause the config file generator
to pass (mostly) silently with only a small message going to
stdout. If we can't import a module that seems like it is a bad
thing so lets just bail.

Add block device handling to build_and_run_instance

If we have block device mappings we want to prep them and pass them to
the virt driver spawn method so they can be attached to the instance.
If there's a failure during the instance creation the volumes will get
cleaned up.

A failure to prep the block devices will abort a build because it can't
be built as desired and the failure is not likely to be related to the
compute node itself.

On an instance build failure we make an attempt to clean up the block
devices for the instance.  If that fails we are left in a bad state and
will not attempt to reschedule the instance.

This is one part of a series of patches to build up the
build_and_run_instance method.

Allow _sync_power_states periodic task to hit slave DB

This commit allows those who have slave_connection configured
to have reads from _sync_power_states hit that connection. This
change does not affect anyone who doesn't have a slave. The
behavior remains the same for them.

Correct update extension point's check_func for v3 server's controller

When loading update extension point, it should check the extension has
'server_update' function. But current code check with wrong function
name 'server_resize'. And this patch adds testcase for servers extension
point.

Enable extension access_ips for v3 API

This patch enable extension access_ips, remove old 'access_ip_*'
attributes and related unittest from servers core. And remove
old attributes from api samples.

xen tests: replace assertEquals with assertEqual

In Python 2.6, both assertEqual and assertEquals are
convenience aliases to failUnlessEqual.

In Python 3, failUnlessEqual is explicitly deprecated.

Adds upper bound checking for flavor create parameters

The flavor-create API does validation that root_gb and
other integer values are positive integers but it doesn't
do an upper bounds check to make sure they aren't longs.
If a user tries to create a flavor with an integer value
that is bigger than an int, the python int() method
(used in the validation) will just convert it to a long but
the database model for InstanceTypes defines the column as
an Integer (not a BigInteger) and then the database has
to handle the value.

This changeset adds upperbounds checking for memory_mb,
vcpus, root_gb, ephemeral_gb and swap.

Also adds missing testcase for ephermal_gb validity

Add InstanceList.get_by_security_group()

This provides a way to get a list of instances that are in a given
security group. This alternative to SecurityGroup.instances is
much simpler and avoids the potential for passing around a
SecurityGroup object with a ton of Instance objects attached.
