Code Issues Proposed changes

Retry `set|get_link_attribute(s)` if the interface is not present

Browse Source 
After some interface operations (in particular the
``IpLinkCommand.set_ns`` operation), the network interface is
temporarily not present in the destination namespace. This patch
retries the interface "ip link set|show" command in that case.
