The incorrect output of "nova show" when VM has long user data

[Timur Nurlygayanov]

Steps To Reproduce:
1. Create VM "test" with large user data
2. Execute in CLI:
nova show test

Expected Result:
We can see the default output of nova show command

Observed Result:
All fields are too large, the output of nova show command takes several pages with many empty lines.

Example of output:

root@node-1:~# nova show 09836461-4a32-425d-a8e4-c06cfd29bfe6

New argument "--wrap" is added for "nova show" command to wrap the output. The default wrap length is set to 80 now.

Usage:
nova show --wrap 60 <server-id>
nova show <server-id> <---- Default to 80 now.

Due to unit testing failures the default wrap has been modified to 0 instead of 80 (specified in #3); The end user now need to specify the wrap argument, if he/she need to see the output specific to the display screen.
