[QGIS-Developer] New QEP: Kill evis

[Nyall Dawson]

Please see https://github.com/qgis/QGIS-Enhancement-Proposals/issues/176
for a proposal to kill the unmaintained legacy evis plugin for QGIS
3.14.

It's completely unmaintained and full of legacy code, with zero
integration between the plugin and the rest of QGIS. If we kill it for
3.14 then it gives organisations time to adapt (and possibly develop a
3rd party plugin version if desired) prior to the next LTR release
(3.16).

There has been NO changes made to this plugin (aside from fixes to
avoid breaking QGIS compilation) for over 10 years. In 2010 a bug fix
was made to this plugin. In the following 10 years the ONLY changes
have been compilation fixes.

We've previously put out calls for interest in community members
stepping up to maintain this plugin, with zero interest.

Let's officially kill it and move on :)
