Provides a nightly image for che-theia image on branch 7.0.0

Description

There is a 7.0.0 branch in che-theia for stabilizing che/theia used for 7.0.0 GA

but AFAIK there is no nightly image built from that branch so any new commit to 7.0.0 is not used on che master branch (7.0.0 branch)

So if the tag is only occurring at the end it might not work at all and people are not using the latest state.

Before che:master was using che-theia:next but it can’t be the case anymore as process it to have something as stable as possible.

I think we can close this issue, che-theia:7.0.0-next is updated on each commit in che-theia 7.0.0 branch, so we don’t need to have nightly image.

@vparfonov for tagged versions we replace aliases by the real versions so latest inside 7.0.0 will still have 7.0.0 everywhere ( a tag is a fixed name) but SNAPSHOT, nightlies, etc, all are for development purpose.

the backend for 7.0.0-rc-4.0 and for 7.0.0 if you use che latest at some point you’ll get 7.0.0-RC4 and then 7.0.0 but you’ll never have a mix.

if you use ‘latest’ then you’ve the latest stable version of che, latest stable version of theia, etc and for testing you would have the testing version of che, etc if you use nightly then you should have nightlies everywhere, etc.
