Add sample admin_{user,tenant_name,password} to default configs

[Shuichiro MAKIGAKI]

I suggest following changes to etc/trove/api-paste.ini:

+admin_tenant_name = %SERVICE_TENANT_NAME%
+admin_user = %SERVICE_USER%
+admin_password = %SERVICE_PASSWORD%

Other OpenStack components also have the same configs as default.

admin_token is removed by Bug #1299332, but I think adding admin_{user,password,tenant_name} instead of admin_token is reasonable. (This is also mentioned in Bug #1299332 by Thomas Goirand.)

I think changing api-paste.ini is enough, and changed description.

    Add sample admin_{user,tenant_name,password}

    Other OpenStack components have the same configs in api-paste.ini.
    admin_token was removed by Bug #1299332, and admin_{user,password,
