Allow request timeout to be specified.

Add a new cli argument (--timeout) which
is by default 600 seconds which will be
set in the requests library so that timeouts
can occur correctly.

Ensure list output function can support non-sorting printing

Ensure list printing function in utils can handle non-sorting
calls. Allow result list can be formatted and outputted without any
sorting field, keep natural order to the list printing. Adding necessary
checking to avoid prettytable (0.6.1 for me) exception: "Invalid field
name: None!".

Allow for image selection using the metadata properties.

Instead of forcing users to remember a image name and/or uuid
instead allow them to specify a image metadata property to 'key'
off of.

For example:

I want to boot a image of ubuntu. This could now be a property
set in the image metadata and the following could be used to
find said image.

$ nova boot my-vm --image-with type=ubuntu

Now that user does not need to care what ubuntu version is being
selected or what the uuid is or what the image name is, they just
know that some image with ubuntu will likely get selected.

make print_dict split strings with newlines into multiple rows

When printing a dict e.g. "nova show" one of the properties
is "fault". When the user is admin, "details" of the fault
is shown, which includes a backtrace. This causes the
printing of the table to be unreadable as the backtrace
overflows the table row. This patch adds a separate row
for each substring after splitting on newlines.

ClientExceptions should include url and method

Fixes Bug 1103557.
novaclient abstracts out http request from user/client
making it unknown to user what root cause behind nova client
exceptions being raised. By including url and method in exception
handling, this allows user to handle accordingly.

Check tenant_id's format in "nova quota-update"

Fix bug 1088835
"nova quota-update" command is executed without checking the format of
the tenant_id argument. The tenant_id should be in the format of UUID.
The tenant_id of quotas should be in accord with the form of keystone's
tenant_id. So this patch checks the format of the tenant_id when "nova
quota-update" command is executed.

_get_secgroup returns first group even if multiple groups match

Nova's security group api layer ensures that a given tenant is not able to
create multiple security groups with the same name. That said, if one is the
admin user and does:
"nova secgroup-delete <secgroup that has a duplicate name as another tenant>"
The first security group that is returned with that name will be removed,
which might not have been what the user intended to do. In addition, quantum
allows multiple security groups to be created with the same name therefore
this change is needed to ensure the correct behavior when nova has a quantum
security group proxy.

Fixes bug 1105542
