Dashboard: Display error mark about Che 6 workspaces

[slemeur]

Description

Che 6 based workspaces are not going to remain compatible with Che 7.
Dashboard will need to allow a user to know if the workspace is still working on not.

In the list of workspaces:

• We should display a visual indicator to notify the user that the workspace will not work anymore.
• We would provide a link on documentation explaining how to create a workspace in Che7.
• We would remove the ability to start the workspace.

In the workspace details:

• We will display a message (in the header) explaining that the workspace is not compatible and needs to be converted as a Che 7 workspaces. Including a link to the documentation on how to do that.

@slemeur Could you add some details, mockups?

[slemeur]

@olexii4 Unfortunetaly I'll not have time to provide you mockups. What kind of details do you need?

Ok. Thanks.
@slemeur You wrote, "We should display a visual indicator to notify the user that the workspace will not work anymore". Could I reuse an existing one(add a black color and a tooltip)? WDYT?

[slemeur]

Try to find something more obivous and easier for the end-user. (maybe display the message "This workspaces is not compatible with this version of Che")

@slemeur Is this issue include creating documentation part about how to convert Che 6 as a Che 7 workspace? I cannot find it.

Could you help me with the needed links?

[olexii4]

@slemeur Should we remove CHE6 workspaces from the recent workspaces sections and factory workspace resources?
