Remove akka dependencies from `runtime` project

[Akirathan]

runtime project, and thus runtime.jar fat jar, transitively contains akka dependencies, for example from runtime --> downloader --> akka. We should remove akka from downloader and implement the downloading by some simple http component from JDK (or Scala's standard library).

akka is unnecessarily heavy-weight, it comprises of a lot of classes that are loaded just because of few simple HTTP requests.

### Tasks
- [x] Ensure there is are no `akka` classes in `runtime.jar`
- [x] Remove `akka` from `downloader` (#8953)
- [x] Split `connected-lock-manager` into two projects

Pavel Marek reports a new 🔴 DELAY for today (2024-02-15):

Summary: There is 10 days delay in implementation of the Remove akka dependencies from runtime project (#8222) task. It will cause 10 days delay for the delivery of this weekly plan.

Will probably have to refactor that PR to use Apache HttpClient instead of pure JDK.

Delay Cause: Issue with native image build on Windows, also, peers don't like the custom usage of JDK

Pavel Marek reports a new STANDUP for today (2024-02-15):

Progress: - native image build of launcher is failing on Windows, but works on Linux.

• Radek cannot reproduce that on his Windows machine.
• Let's increase logging and see what is wrong on the CI.
  • Ongoing discussion about using Apache Http rather than pure JDK solution. It should be finished by 2024-02-22.

Pavel Marek reports a new STANDUP for today (2024-02-16):

Progress: - Still cannot figure out the native image build failure on Windows.

• Capturing output from the native image build, increasing verbosity, restarting the job... It should be finished by 2024-02-22.

Pavel Marek reports a new STANDUP for today (2024-02-19):

Progress: - The build failure on the Windows was caused by the cmd line being too long.

• Fixed by adding arguments to native-image via an argument file.
• Finally merged. It should be finished by 2024-02-22.
