Receive messages (like maintenance messages) from servers

[ferventcoder]

And display them to user.

This involves work with the server side as well.

One of the many reasons for this is to less confuse users like me figuring out the cause of problems, for instance when today figuring out the cause for the behaviour I will quote at the bottom of this comment.

I started the searches below to find out some mentioned https://status.chocolatey.org that had the maintenance Window then got a response when tweeting about it and getting directed to this issue.

I will link to this issue from some related issues during my search so it will be easier for others to find this issue and upvote it.

Since https://status.chocolatey.org/ knows about status, I guess that by now a bit of the server side work already is in place making it a tiny bit easier to add a feature like this (which likely is not easy to write test code for given there is client-server interaction involved).

Maybe split this into an approach of smaller steps like:

1. for 503 and time-out on chocolatey server requests have choco suggest to look at https://status.chocolatey.org
2. later have choco interrogate server side of https://status.chocolatey.org and inform of a current maintenance window.

The searches I used were for issues containing:

• The remote server returned an error: (503) Server Unavailable. Service Unavailable)
• The operation has timed out

They were based on this choco output:
