[Breaking] Drop support for Ember < 3.16, Node 6+8

[simonihmig]

Using ember-cli-update to update dependencies and drop support for old versions.

Seems Travis is not enabled by default anymore for OSS projects. Added a commit that sets up Github Actions. Although that will only get triggered once the config is in master!

Hey @davewasmer, could you have a look at this (and #96) please?

[davewasmer]

@simonihmig Unfortunately I'm no longer supporting any production Ember apps at the moment, so I'm not comfortable doing the code review / planning / maintenance here. I know @Exelord had taken over much of the work on this addon - perhaps they could chime in?

[Exelord]

Looks good to me :) Though, before a release the new CI setup needs to be verified.

[simonihmig]

@Exelord seems you got into trouble with the Guthub actions config, sorry about that!

The config I used worked nicely when used with yarn. I quickly changed yarn to npm, but apparently missed changing to npm run, which you then fixed. Other than that it seems it is the same error that does not go away, even with your many changes afterwards: Cannot find module 'internal/util/types'. Looking at remy/nodemon#1124, it seems it is related to having an old version of npm, which indeed in CI is v3.5.4. Any idea why it is that old?

Other than that, we could switch to yarn maybe?

[Exelord]

yeah 😅 was trying to solve it but I failed at the end. The weird thing is, only the ember-try tests fail. It might be related to npm, thanks for pointing this out! I will try to upgrade it, otherwise will fallback to yarn (though I would like to stick to native)

[Exelord]

It looks like somehow ember-try is using wrong npm version, though the latest is installed 🤔
