CLOUDSTACK-8758: Handle redirects in communication with NXS controller (a.k.a.
Nicira NVP)When an NSX controller node is part of a cluster it will redirect
API calls to the master controller. Because the ACS management server does not
follow such redirects, if there is a change of master within a NSX cluster, the
NSX device (a.k.a. NiciraNvp) needs to be reconfigured (via the management
server DB).
The goal of this PR is to enable ACS management server to follow HTTP redirects
sent by NSX controllers. However, other changes were made to the cloud-utils
module that provides the REST client that the NSX plugin uses.
Cosmetic changes:
* Upgrade maven module structure for cloud-utils and cloud-plugin-netowkr-nvp
to comply with maven default
* Several refactorings on both modules to consistently format the code, remove
unused code, declare final when possible, remove auto generated comments, etc
Other changes:
* Upgrade HTTP library used in REST client to version 4.5 of Apache HTTP
Components
* Implement generic REST client that supports HTTP redirects
* Implement NSX specific REST client
* Simplify NSX api implementation
* Previously existing unit tests for both the REST client and NSX api were
either maintained in the same test classes, moved to new test classes (because
code under tests also moved), or removed (because code under tests was also
removed)
* New Marvin tests for NSX controllers
Testing:
* Ran all unit tests present in the project
* Ran Java Integration tests for NSX api targeting both a master and a slave
controller
* Ran new Marvin test for NSX controller
* Manual inspection of logs to confirm redirection is taking place
* pr/737:
Use NSX specific RestClient in API implementation (NiciraNvpApi)
Refactor NSX api implementation (NiciraNvpApi)
Add NSX specific RestClient implementation
Delegate HTTP protocol activity in RESTServiceConnector to RestClient
Add basic RestClient implentation based on HTTP Components 4.5
Code clean up in cloud-plugin-network-nvp project
Code clean up in cloud-utils project
Refactor cloud-plugin-network-nvp project into Maven default structure
Refactor cloud-utils project into Maven default structure
Fix unit-test library dependencies
Add Marvin test for Nicira NVP plugin
Create Nicira NVP devices and enable plugin at deploy

> When setup in a cluster, NSX controllers will redirect calls to the cluster
> master. However, the NiciraNvp plugin does not handle those redirects
> correctly. The underlying HTTP client will transparently redirect calls, but
> the plugin will aways override the target host to the initial value.
> The underlying HTTP library being used at the moment is Apache HTTP Commons,
> which has been superseded by Apache HTTP Components which introduces a new
> architecture. This library should be upgraded to the new architecture since
> this will make it easier to transparently handle redirects,
