Show quota 'in_use' and 'reserved' info

We need show all the quotas related info, including 'in_use' and
'reserved'--not just the limit--when executing 'nova-manage project
quota'.

Fix migrating instance to the same host.

In current code logic, Migration to the same host is allowed which is
meaningless.

In the patch, a Conf flag 'allow_migrate_to_same_host' is added and set to
false as default. When 'allow_migrate_to_same_host' is false, the current
instance host will be added into filter property 'ignore_hosts' to avoid
migrating instance to the same host.

Convert host value from unicode to a string.

The memcached API expects string format, not unicode.
Convert the host value to a string before creating
the cache_key and passing it to memcached.

Ensure only pickle-able objects live in metadata

Conductor api has been added to InstanceMetadata object, but it cannot
be serialised. This breaks storing metadata in memcache, because the
information needs to be passed through pickle.

Since the field was not used outside of the constructor, it can be
removed to fix the problem.
Also add a test that pickles a sample InstanceMetadata to catch similar
failures in the future.

Use Cluster reference to reduce SDK calls

The vmware compute driver retrieves the cluster reference
for every spawn and volume operation. The solution is to
retrieve the reference once from the __init__() of
vmwareapi/driver.py and reuse the same in other methods.
This will reduce the number of VI SDK calls made.

Accepts aws-sdk-java timestamp format

The aws-sdk-java timestamp format is "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
which contains millisecond representation. However, the current
implementation does not accept this kind of format.

References:
https://github.com/aws/aws-sdk-java/blob/master/src/main/java/com/amazonaws/auth/QueryStringSigner.java#L173

Adds ability to parse this format in ec2utils.is_ec2_timestamp_expired.

improve handling of an empty dnsmasq --domain

Currently all domains passed through the dnsmasq --domain option,
are single quoted.  It's not fully understood how dnsmasq handles
single quotes in this situation, so it's safer to just avoid the
--domain option in this case.

Query quantum once for instance's security groups

This patch adds the method get_instance_security_group_bindings()
which returns all the instance_id's and security groups for a given
tenant. This method is then used to avoid querying quantum for it's
security groups when using GET /v2/<project_id>/servers/detail.

Better iptables DROP removal.

With the introduction of configurable iptables DROP rules in
nova-network, we need to cleanup possibly more than one drop
rule, depending on what DROP action was in place when the rule
was created. This patch handles this for the simple case where
the drop action has just been configured. More complicated
scenarios will need to be handled manually.

Return proper error message when network conflicts

Fixes bug 1158075
When creating a network which is already existing, we got
an internal server error which can't show the error reason.
This patch returns conflict error(HTTP 409) instead of
internal server error(HTTP 500), so that users can know
the error reason from the error message.

Remove gettext.install() from nova/__init__.py

The gettext.install() function installs a builtin _() function which
translates a string in the translation domain supplied to the install()
function. If gettext.install() is called multiple times, it's the last
call to the function which wins and the last supplied translation domain
which is used e.g.

 >>> import os
 >>> os.environ['LANG'] = 'ja.UTF-8'
 >>> import gettext
 >>> gettext.install('keystone', unicode=1, localedir='/opt/stack/keystone/keystone/locale')
 >>> print _('Invalid syslog facility')
 無効な syslog ファシリティ
 >>> gettext.install('nova', unicode=1, localedir='/opt/stack/nova/nova/locale')
 >>> print _('Invalid syslog facility')
 Invalid syslog facility

Usually this function is called early on in a toplevel script and we
assume that no other code will call it and override the installed _().
However, in Nova, we have taken a shortcut to avoid having to call it
explicitly from each script and instead call it from nova/__init__.py.

This shortcut would be perfectly fine if we were absolutely sure that
nova modules would never be imported from another program. It's probably
quite incorrect for a program to use nova code (indeed, if we wanted to
support this, Nova code shouldn't use the default _() function) but
nevertheless there are some corner cases where it happens. For example,
the keystoneclient auth_token middleware tries to import cfg from
nova.openstack.common and this in turn causes gettext.install('nova')
in other projects like glance or quantum.

To avoid any doubt here, let's just rip out the shortcut and always
call gettext.install() from the top-level script.
