Rust authority bootstrap

[nbuffon]

What's new

New function to create a Configuration from bootstrap sequence
The bootstrap sequence provide services' URL and credentials, any of these information already present in the configuration file
All the other fields that are unrelated to services connection are still read from the configuration file and set in the Configuration object

closes #185
closes #161

How to test

1. Edit examples/config.ini and
   1. Fill the [bootstrap] section with the proper endpoint and credentials
   2. Remove the [mqtt] section
   3. Remove the ``telemetry]` section
2. Apply the joined patch to make the copycat example using the bootstrap sequence

   cd rust
   wget https://github.com/user-attachments/files/17728759/copycat_bootstrap.txt
   mv copycat_bootstrap.txt copycat_bootstrap.patch
   git apply copycat_bootstrap.patch
   

3. Start the copycat example

   cargo run --example copycat --features geo_routing --features telemetry
   

   => The example runs and receives messages

Why not include the example of copycat with bootstrap to the current PR (with another name to keep existing copycat)? As bootstrap is now a feature of the lib.

Problem is that it requires a running bootstrap server and for now the code is private and the platform is not deployed as publicly usable
So I did patch the example to test the bootstrap, if you prefer I can add a dedicated example but it is not possible for external users to run it
In comparison the telemetry example already requires to edit the config.ini file to fit the OTLP collector instance (which is not very example friendly as an example should be able to run without any modification) but you can easily run your own collector using official Docker images
This is not yet possible for the bootstrap so I decided not to provide an example yet, the idea is to provide a public instance of the platform which is still work in progress

See answer in the thread for station_id field in [bootstrap] section

[nbuffon]

Changes are pushed, station_id now correctly comes from the [station] section
