Speed up posh tests

[FerdinandSpitzschnueffler]

Brief feature description

Some of our tests, e.g. when publisher subscriber communication is tested, call InterOpWait provided by the RouDiEnvironment to ensure that the discovery loop has been run through. Adding a function to the RouDiEnvironment to trigger the discovery loop manually would make these tests faster and more reliable.

In addition quite a lot of time is spent in memset to zero the shared memory. This time could be reduced by having a minimal mempool config for the tests. In addition, the introspection mempools should also be configurable via the RoudiConfit_t

Tasks

• add manual trigger for the RouDi discovery loop (e.g. via a WaitSet and a UserTrigger)
• provide a RouDiConfig_t with a minimal memory footprint
• add an option to RouDiConfit_t to configure the number of chunks for the introspection

@FerdinandSpitzschnueffler I discovered that there are more issues than the discovery loop and updated the issue accordingly.
