When nova-network raises NoMoreFixedIps a stacktrace is thrown

Since this is an expected error, it should not be stacktracing, only logging a warning/error

[Wei Wang (damon-devops)]

The function allocate_fixed_ip() in network/manager.py should be fixed.

    Improved error logging in nova-network for allocate_fixed_ip()

    When a Nova deployment runs out of fixed IP addresses, allocating
    another IP ends with stack trace without clear explanation.
    To prevent such behavior this patch introduces few try-except blocks
    that writes appropriate error message to the log file and return
    better error code via API instead of stack trace.
