Support publishing snapshot releases to Central Portal

[solrudev]

Now that the issue with snapshots publishing is resolved on Sonatype's side, we can add support for it.

Closes issue #891.

Thanks for the contribution. I should manage to get a release out with this during the next week

Is it? I keep getting 403 with some files going through.

When you tried it, did you have the changes from this PR? It sounds like maybe you're still using the latest release which doesn't have these fixes yet (one of which is related to authentication)?

[bruderj15]

Thanks for the fast reply.
I am actually using the maven plugin central-publishing-maven-plugin with v.0.7.0.

@bruderj15 Last I've checked everything seemed normal. If you have problems, send an email to Sonatype. After I've communicated with them about the issue, it got resolved for me and, as I saw, for others too.

Also, if credentials are not present, it'll return 401 code, not 403, so it's not a problem in the plugin, especially considering that you're using the official one.

Thanks for adding this functionality @solrudev. Really useful for a project I'm working on!

@gabrielittner Are there expected dates for an RC of 0.31.0?

I should really have checked the state of this before migrating my project. 😭 I just migrated my project to Central Portal after seeing they now support SNAPSHOTS. I'm currently stuck due to this limitation unless I move to a different publishing plugin. With my namespace migrated there is no going back.

Any chance we get a release soon enabling the SNAPSHOT publishing?

Sorry for the delay, I'll try to cut a release in the next days.
