Add support for LOCAL_DOMAIN

[uda]

Problem

I want to install Mastodon on a subdomain while allowing users to use their user@rootdomain identity, this is supported by mastodon using the LOCAL_DOMAIN environment variable

• Implement what is decided in #372

Solution

I added an argument local_domain that if empty uses the main domain argument

NOTICE: this currently accepts arbitrary local_domain value, since I was unable to have an empty value from domain argument type, which would allow me to add a .well-known nginx path handling, meaning that the user will need to add manual .well-known redirects (List of URLs)

It looks like the test is timing out, why does it take 180 minutes?

I've did it once upon a time #311 . it works when manually configuredbutb I lose my work because of lake of understanding github ;) I can help as soon as I go back home. My hope is to use mastodon as a activity pub feeder to centralize fediverse subscriptions.

The only problem I had was when I would subscribe from my mastodon to my own peertube Chanel.

And I had problem with timeout testing too.

Just for registry

To install your repo in my specific case (yunohost in LXC low memory container hosted on armhf arch) i had to do first : #354 then as described in https://github.com/mastodon/mastodon/issues/15751 in my case

echo /usr/lib/arm-linux-gnueabihf/libjemalloc.so > /etc/ld.so.preload
sudo apt install libjemalloc-dev

... more later ...
