Make Welcome message configurable

[chaoran-chen]

I think that it would be nice if we can make the Welcome message on the landing page configurable. At the moment, it always says

Welcome to {website name}, a system for sharing pathogen genome data.

Instead, I'd suggest adding a config like welcomeMessageHTML that an admin can set to overwrite this message.

Hmm, I can see it being useful in principle. Should it be directly in HTML (as the suffix on your suggested config option suggests)? Would it still be possible to use website name as a template variable somehow?

HTML would be most flexible and we already have a few places where people can insert HTML through the config such as additionalHeadHTML and I think also for the yellow top banner (that shows up for some instances).

Would it still be possible to use website name as a template variable somehow?

By default, if the config is not set / set to null, I'd say that we will still display the text as now. This will be done directly in the website code, meaning that the new config will be considered optional for the website application. If the admin defines a message, I don't know whether they can do some templating through Helm magic but I wouldn't implement a feature specifically.

To be explicit, I think you're talking about this, correct?

Yes, exactly! :)
