Install and use plugin on previously deployed environment

[Bulat Gaifullin]

User story:
As a user who is experimenting in my OpenStack environment, I want to install application level plugins (non-core functionality) on top of my environment after it has been deployed so that I am not constrained only to plugins that were available (and I decided on) at the time of the deployment.
Description:
Some features (like VIP creation by a plugin) need to be reviewed to ensure they can be used by plugins post-deployment - if these features cannot be used, we need to backlog Launchpad items as dependencies of this story to address changes
We need to support a limited class of plugins that can be installed and/or modified after deployment. For example, a customer would like to add monitoring or log analytics. For some plugin types, such as SDN, post-deployment installation will not be possible.
"Ex.1: During deployment customer decided add Zabbix - have to
redeploy instead of add
Ex.2: Cisco ACI plugin was late, entire deployment had to wait
since no way to add plugin after deployment is started"
Acceptance criteria:
Any application level plugin can provide the same functionality if added after the environment is deployed as before
Current application level plugins - Zabbix, others?

Enable creation of fake plugin

example_v4 += example_v4_hotpluggable with hotblug support
Required for postdeploy plugin installation feature check.
This is non standard behavior of plugin, so we have copy-paste plugin and modify it.

    Minor refactor

    1. SingletonMeta -> modified to allow handling multiple classes and moved to metaclasses too.
    2. @logwrap : process asserts too

    Changes reason:
     @logwrap was changed during test debug (was assert in wrapped function
     and stacktrace was not enough for reason understand) and moved out of
     test changest due to not mandatory for this test.
     Pros: Now assert, raised in wrapped function is recorded in log with
     details.

     SingletonMeta: was changed as "nice to have" during work on plugin
     helpers. Later plugin helpers was moved out of SshManager, and all code
     changes was moved to this changeset.
     Pros: Single way for handling the same tasks in different places.
     Previously SshManager used Metaclass, which could not be reused for
     more, than one class and Environment used __new__ directly written
     in class code.
