Solve the problem that the neutron client uri request is too long

Problem:

When the O & M personnel use the administrator to execute the neutron security-group-rule-list security group rule query, because there are too many security group rules, our neutron-client code version is old, error 414 is displayed.

Solution process:

Check the new code of the community. The bug has been fixed.

Fix listing security group rules

When querying security group rules, this patch splits the uri into multiple http requests if it finds that the uri is larger than 8192 bytes.

After the backport is returned, run the command again. neutron-server returns error 400.

</Body>

When the neutron client executes the security-group-rule-list command, it first sends a request to obtain the security-group-rules and obtains the security-groups id, then, send the request again based on these IDs.

View the neutron server log and find that the neutron server did not receive the second request, but the uri length does not exceed eventlet. wsgi. server's default maximum length of 8192.

A bug was raised to the community, which was not confirmed by the community. Adjust the chunk_size in the code by yourself, so that the uri of a request is not that long, and the neutron-server returns the result correctly.

I am not sure whether this problem is caused by the master version and python-eventlet version I. Since the community Test has passed, it indicates that there should be no problem on the master, but it has not been verified yet. (After testing on the master version, the neutron server returns normal)
