Feature/509 remove install of v2 headers

[pnoltes]

This PR removes the installation of the deprecated headers (those without the celix_ prefix) from the utils and framework libraries.
This is a task in #509.

Additionally, the PR removes the installation and usage of the v2 headers for the shell_api, log_service_api, and pubsub_spi libraries.
As a consequence, the shell_bonjour and psa_udp_mc bundles, which relied respectively on the v2 shell_api and v2 pubsub serializer api and both hasn't been maintained, are also removed.

Lastly, the remote service admin bundles/libraries have been using the service_reference and hashmap in their API/SPI. As a result, they are not currently usable downstream. Addressing this requires a significant effort; thus, for this PR, I've disabled the Conan test package test for RSA. This will be addressed in a future PR.

I used Celix in my day job. IIRC, we used some deprecated APIs for some reasons.
Before merging this PR, I would like to have a case-by-case analysis of these usages to make sure our new API can still satisfy these needs. For example, why service_reference is needed for RSA? Without service_reference, how to implement the same functionality with 3.0 API? More deprecated API usage scenarios will be added next week.

If the current 3.0 API can not address some requirements, it is a good chance to have some discussions before actually removing deprecated 2.0 APIs.

@xuzhenbao Please have a look at the RSA part.

I understand. My proposal is to reintroduce the framework v2 headers install and RSA conan create test in PR.
We can then discuss the removal of service_reference, etc and the future of RSA, before removing all v2 headers.

It's a good idea to temporarily reintroduce framework v2 headers.

Now that 2.4.0 is available, I am working on introducing it into my day job projects.
After that I will be able to provide precise feedback about the current usage of deprecated APIs in these projects.

@xuzhenbao Please have a look at the RSA part.

Given that the removal of the deprecated headers and therefore the refactor RSA will be done later, I will merge this PR.
