The configuration is not pretty displayed in Graylog v5

[frantz45]

With Graylog v5.1.4 and Logging Alert v5.1.0 the configuration is not pretty displayed:

As you can see the name is too long.
I propose to change this ugly long name by "Logging Alert".

The problem is that the name which is displayed is hard-coded inside the graylog2-server interface code-base, rather than brought by the plugin. So graylog2-server must know the plugin before hand.
More precisely, the name which is displayed on the configuration page is the displayName (https://github.com/Graylog2/graylog2-server/blob/5.1.3/graylog2-web-interface/src/components/configurations/PluginsConfig.tsx#L93)
To compute the displayNamegraylog searches (https://github.com/Graylog2/graylog2-server/blob/5.1.3/graylog2-web-interface/src/components/configurations/PluginsConfig.tsx#L88) in the table of predefined plugin display names https://github.com/Graylog2/graylog2-server/blob/5.1.3/graylog2-web-interface/src/components/configurations/PluginsConfig.tsx#L45. If it doesn't find it there, it uses the configType.
The legacy collector system is present in the table of predefined plugins display names, but not our plugin (obviously) :(
The list of plugins graylog knows is listed here: https://github.com/Graylog2/graylog2-server/blob/5.1.3/graylog2-web-interface/src/components/configurations/ConfigurationTypes.ts#L29

This is quite a hack. We could open a ticket for Graylog...
