Credit where credit is due; I inspired myself by looking at the yunohost docs

I try to be inviting to new developers and guide them in their first steps into Akkoma development.
I try to keep the page itself as short as possible and link to relevant places.
That way people can quickly skim over parts that they don't need, while people who do need more can simply follow the links.
I experienced that it may be better to tell pgtune you have lower resoures than what you have when you have other services running.
I added that now.
I also moved the examples as part of the pgtune section.
This adds an option to the prune_objects mix task.
The original way deleted all non-local public posts older than a certain time frame.
Here we add a different query which you can call using the option --keep-threads.
We query from the activities table all context id's where
1. the newest activity with this context is still old
2. none of the activities with this context is is local
3. none of the activities with this context is bookmarked
and delete all objects with these contexts.
The idea is that posts with local activities (posts, replies, likes, repeats...) may be interesting to keep.
Besides that, a post lives in a certain context (the thread), so we keep the whole thread as well.
Caveats:
* ~~Quotes have a different context. Therefore, when someone quotes a post, it's possible the quoted post will still be deleted.~~ fixed in AkkomaGang/akkoma#379
* Although undocumented (in docs/docs/administration/CLI_tasks/database.md/#prune-old-remote-posts-from-the-database), the 'normal' delete action still kept old remote non-public posts. I added an option to keep this behaviour, but this also means that you now have to explicitly provide that option. **This could be considered a breaking change!**
* ~~Note that this removes from the objects table, but not from the activities.~~ See AkkomaGang/akkoma#427 for that.

**TODO**
1. [x] **Question:** Is it OK to keep it like this in regard to quote posts? If not (ie post quoted by local users should also be kept), should we give quotes the same context as the post they are quoting? (If we don't want to give them the same context, I'll have to see how/if I can do it without being too costly)
* See AkkomaGang/akkoma#379
2. [x] **Question:** the "original" query only deletes public posts (this is undocumented, but you can check the code). This new one doesn't care for scope. From the docs I get that the idea is that posts can be refetched when needed. But I have from a trusted source that Pleroma can't refetch non-public posts. I assume that's the reason why they are kept here. I see different options to deal with this
1. ~~We keep it as currently implemented and just don't care about scope with this option~~
2. ~~We add logic to not delete non-public posts either (I'll have to see how costly that becomes)~~
3. We add an extra --keep-non-public parameter. This is technically speaking breakage (you didn't have to provide a param before for this, now you do), but I'm inclined to not care much because it wasn't documented nor tested in the first place.
3. [x] See if we can do the query using Elixir
4. [x] Test on a bigger DB to see that we don't run into a timeout
5. [x] Add docs

Some users post posts with spoofed timestamp, and some clients will have issues with certain dates. Tusky for example crashes if the date is any sooner than 1 BCE (“year zero” in the representation).
I limited the range of what is considered a valid date to be somewhere between the years 1583 and 9999 (inclusive).
The numbers have been chosen because:
- ISO 8601 only allows years before 1583 with “mutual agreement”
- Years after 9999 could cause issues with certain clients as well

Faced with this issue today, Pleroma responds with status 400 (Bad request) if Exiftool.StripLocation is added to the list of filter modules for uploads. Here is logs:

See AkkomaGang/akkoma#350 (comment)
When making quotes through Mast-API, they will now have the same context as the quoted post. This also results in them being showed when fetching the thread. I checked Misskey to see how it's there, and they show the quotes there as well, see e.g. <https://mk.toast.cafe/notes/98u1g0tulg>.
