remove old swift port 8888 in sample script

[Kun Huang]

In <keystone-repo>/tools/sample_data.sh, it generates many data like endpoint for nova, glance and also swift. In old swift documents, they use 8080 port as swift proxy server running with tempauth, and port 8888 for swift + keystone environment. It's very old, and now in swift there is no document, sample, or default value using 8888. After running sample_data.sh for generate an example enviornment, we have to switch swift port from 8080 to 8888 (default value and sample conf in swift always use 8080). For a newbie, the sample_data.sh doesn't work dericetly from him. So using 8080 here could help this script build an easy and fast test environment.

    remove 8888 port in sample_data.sh

    Swift now doesn't use 8888 port as any default service. And the origin
    sample_data.sh always let new users to fail and modify swift bind port.
    So switching 8888 port here to 8080 could generate sample data without
    any change for building swift + keystone environment.
