[Feature-Request] Show autotrigger snippets in completion

[atticus-sullivan]

Hi, sometimes I forget about autotriggered snippets so it would be nice to be able to display autotriggered snippets in the completion menu of the completion engine as well by introducing a new option for that in the setup or maybe an explicit show option for the snippets function (contrary to the hide option).

There's this PR (though it's outdated for current master) for showing autosnippets, I think the best way would be to set an option in cmp_luasnip.setup()

[atticus-sullivan]

Ah of course. As this is only related to displaying, this should be done in the "adapters" to the completion engines. I'm gonna look into this (in a few weeks). But this changes look a bit complicated (at least at first sight) (have to dig through all the code related to caching first).

[L3MON4D3]

Yeaaah, the caching makes the otherwise pretty straightforward job of turning a list of snippets into a list of completion-items a bit more messy :/ Luckily all items for one filetype are stored together, so it's not horribly complicated

[atticus-sullivan]

Not sure since when but at least for my limited amount of autosnippets, I get them listed in the completion menu of cmp. Thus this issue is solved for me.
