Add a flow formatting framework and one implementation for console
printing using rich.
The flow formatting framework is a simple set of classes that can be
used to write different flow formatting implementations. It supports
styles to be described by any class, highlighting and config-file based
style definition.
The first flow formatting implementation is also introduced: the
ConsoleFormatter. It uses the an advanced rich-text printing library
[1].
The console printing supports:
- Heatmap: printing the packet/byte statistics of each flow in a color
that represents its relative size: blue (low) -> red (high).
- Printing a banner with the file name and alias.
- Extensive style definition via config file.
This console format is added to both OpenFlow and Datapath flows.
Examples:
- Highlight drops in datapath flows:
$ ovs-flowviz -i flows.txt --highlight "drop" datapath console
- Quickly detect where most packets are going using heatmap and
paginated output:
$ ovs-ofctl dump-flows br-int | ovs-flowviz openflow console -h

Add a new python package (just the scheleton for now) to hold a flow
visualization tool based on the flow parsing library.
flowviz dependencies are installed via "extras_require", so a user must
run:
$ pip install .[flowviz]
or
$ pip install ovs[flowviz]

Since on CentOS/RHEL the builds are based on stable branches and not on
tags for debugging purpose it's better to have the downstream version as
version so it's easier to know which commits are included in a build.
This commit adds --with-version-suffix as ./configure option in
order to set an OVS version suffix that should be shown to the user via
ovs-vsctl -V and, so, also on database, on ovs-vsctl show and the other
utilities.
--with-version-suffix is used in Fedora/CentOS/RHEL spec file in order to have
the version be aligned with the downstream one.
