Attaching or modifying a visualizations returns early on, to avoid a situation when a background job is stalled (by other jobs) and eventually the request timeouts.
This has an unfortunate consequence that any error reported in the `UpsertVisualizationJob` cannot be reported as a directly reply to a request because the sender has already been removed from the list.
Added more logs to discover why we get errors in the first place.
Modified the API a bit so that we carry `VisualizationContext` instead of three parameters all over the place.
Bonus:
Modified `JsonRpcServerTestKit` to implicitly require a position so that we get better error reporting on failures.
As discovered in #7224, Json RPC protocol was added to the asynchronous resource initialization stage, as part of #6306, but was not in fact initialized at that point.
Instead it was initialized when the server was started to be able to serve correctly the initialization messages. A classic Catch-22. It was really hard to discover this just by looking at the code, but the profiling clearly showed where the time was spent.
This change splits Language Server's protocol into two:
- the first one accepts `heartbeat/init` and `session/initProtocolConnection`
- the second one enriches it with the full set of supported messages
This shifts the initialization from blocking for 0.5 sec to only ~30ms, and performing the second stage asynchronously.
Closes#7224.

In order to investigate `engine/language-server` project, I need to be able to open its sources in IGV and NetBeans.
# Important Notes
By adding same Java source (this time `package-info.java`) and compiling with our Frgaal compiler the necessary `.enso-sources*` files are generated for `engine/language-server` and then the `enso4igv` plugin can open them and properly understand their compile settings.
![Logical View of language-server project](https://user-images.githubusercontent.com/26887752/215472696-ec9801f3-4692-4bdb-be92-c4d2ab552e60.png)
In addition to that this PR enhances the _"logical view"_ presentation of the project by including all source roots found under `src/*/*`.
This change adds support for Version Controlled projects in language server.
Version Control supports operations:
- `init` - initialize VCS for a project
- `save` - commit all changes to the project in VCS
- `restore` - ability to restore project to some past `save`
- `status` - show the status of the project from VCS' perspective
- `list` - show a list of requested saves
# Important Notes
Behind the scenes, Enso's VCS uses git (or rather [jGit](https://www.eclipse.org/jgit/)) but nothing stops us from using a different implementation as long as it conforms to the establish API.
Related to #1153, implements the first part of the integration, without the
parts that use the runner which will be done next.
Temporarily there are two logger implementations - this will be alleviated with
the next part - when and the direct classpath dependency on the language server
is removed.
Project Manager to stores its metadata inside the project directory,
instead of maintaining the global index. This will allow users to move
and modify files inside the ~/enso directory.
