lack of documentation for pre-built plugins

Problem

From metwork v1.0, mfdata templates have been replaced by "pre-built" (or pre-released) plugins locaded on directory /opt/metwork-mfdata/share/plugins/ on target installation:

$ ll /opt/metwork-mfdata/share/plugins/

There is nothing in the documentation about these plugins.
Indeed it is documented how to install a plugin and how to configure it externally but nothing about theses pre-built plugins (ex templates).

Note 1: Most of them need extra configuration.
Note 2: We must provide a way to "make develop" a pre-built plugin.

Proposed solution

In documentation, provide the list of pre-built plugins and the way to install them with command - ex:

plugins.install --new-name ftpsend_temp /opt/metwork-mfdata/share/plugins/ftpsend-2.2.0-1.metwork.mfdata.plugin

Then refer to the chapter for configuring it.

Workaround - Make develop pre-built plugin

plugins.install --new-name ftpsend_temp /opt/metwork-mfdata/share/plugins/ftpsend-2.2.0-1.metwork.mfdata.plugin
bootstrap_plugin.py create my_own_ftpsend
cp ~/var/plugins/ftpsend_temp/main.py ~/var/plugins/ftpsend_temp/config.ini my_own_ftpsend/
plugins.uninstall ftpsend_temp
cd my_own_ftpsend && make develop
## then you can git init, add, commit, push your plugin to a git repository
