Add add_analyzer functionality

[MartinCornelis2]

Applied the following changes:

• Move the creation of analyzer_group_ and other_analyzer_ from the constructor to a new function initAnalyzers().

• Added a subscriber to parameter events param_sub_ that triggers a callback parameterCallback.

• Check in the callback if this node got any new paramters -> if true, lock the mutex and call initAnalyzers() again.

• Created an add_analyzer node that forwards its own parameters to the diagnostic_aggregator by sending a request to /diagnostics_agg/set_parameters_atomically service

• The add_analyzer looks for all parameters starting with the prefix analyzers., converts them to a parameter_msg and sends them together as one SetParametersAtomically::Request

Example usage:

<node name="add_steering_ecu_analyzer" pkg="diagnostic_aggregator" exec="add_analyzer" >
        <param from="$(find-pkg-share harvey)/param/diagnostic_analyzers/steering_ecu_analyzer.yaml" allow_substs="true"/>
        <remap from="/diagnostics_agg/set_parameters_atomically" to="/diagnostics_autonomy/set_parameters_atomically" />
</node>

perhaps a little more clarity could help with the name. Something like a node_param_ns_,?

Great, please fix the linting (See CI) and rebase of the ros2 branch. Otherwise we cannot forward this PR as it would also contain ros#324

Did you write this code or adapted this from somewhere? If you wrote it yourself, this should be the BV where you work for, so Copyright 2024 Nobleo Autonomous Solutions B.V.

Wrote it myself but just copied the pasta for the notice and forgot to make it Nobleo Technology or whatever it should be, will update.
