[conan-center] Conan v2 support: part II

[uilianries]

This new try brings back the conan center hook support for Conan 2.x

The idea is replace the current conan-center hook for Conan 1.x at some point, as part of Conan 2.x migration in CCI. It will executed with the current conan-center in CCI, but separated and only with Conan 2.x. At some point, we will stop conan-center hook with Conan 1.x and keep only with Conan 2.x (date TBD).

Several changes have been made, including:

• Add new tests for each hook
• Removed outdated/not used hooks for Conan v2
• Adapted Jenkins to test Conan v2 with the new hook

TODO:

• Validate with CCI
