[FEAT] Introduce pasqal local (on-prem) setup

[MatthieuMoreau0]

Description of Change

Introduce a new implementation of the QRMI for Pasqal on-prem QPUs. This implementation is mostly inspired from the pasqal-cloud implementation with a few tweaks for authentication.

Munge

This implementation depends on munge to authenticate the user making HTTP calls to the middleware. The auth flow is described in the diagram below:

sequenceDiagram
    autonumber
    participant SpankPlugin as Spank plugin
    participant USER_ENV as User env
    participant Middleware
    SpankPlugin->>Middleware: Prolog - Create session (slurm munge token + user UID)
    Middleware-->>SpankPlugin: Session ID
    SpankPlugin->>USER_ENV: Inject session ID
    activate USER_ENV
    loop User script
        USER_ENV->>Middleware: Queue job (user munge token + session ID)
        Middleware->>QPU: Send job
        QPU-->>Middleware: Job results
        Middleware-->>USER_ENV: Job results
    end
    deactivate USER_ENV
    SpankPlugin->>Middleware: Epilog - Revoke session

Loading

This dependency to munge is unique to the pasqal-local setup, so we introduce a munge feature that can be optionally activated when compiling the qrmi:

cargo build --release --features munge

There is a linked open PR to optionally link munge to the spank_qrmi plugin using a dedicated flag: qiskit-community/spank-plugins#172

Set-up of project looks OK to me :)

I noted down some small nits that we have to remember from the original init of the code base don the cloud version

@MatthieuMoreau0 can you share how you acquire?

Maybe define a new endpoint in Warden and update this behavior within warden later ?

[MatthieuMoreau0]

I want us to define the expected behaviour properly, so I suggest we do this in a separate MR. OK for you?
