RouDi modularisation

[mossmaurice]

Brief feature description

The current modules and classes in RouDi are entangled and sometimes depend on each other. For safety certification a clear structure and concept is needed.

Detailed information

• Replace m_run in CmdLineArgs_t, also see here
• Draft a plan on how to split iceoryx_posh
  • Distinguish between safety and community building blocks
    • RouDi::monitorAndDiscoveryUpdate() needs to be removed for static discovery (see this discussion)
    • Create objects in shared memory statically during init phase
• Implement split of iceoryx_posh
• ProcessManager::ProcessManager shall use separate error codes for each error
• Move RouDI into separate CMake target
• Move namespace roudi contents from iceoryx_posh_types.hpp into roudi cmake target
