add configuration flag to allow self signed cert for relying party

[frhack]

For test/development could be useful to have the possibility to use self signed certs for relying party

Please provide a configuration flag/switch to accept self signed certs.

I successful achieved to register a self signed relying party (https://127.0.0.1:8443/oidc/rp/) modifying the source code of the file spid_cie_oidc/entity/http_client.py as follow:

async def http_get(urls, httpc_params: dict = {}):
async with aiohttp.ClientSession(**httpc_params.get("session", {}),connector=aiohttp.TCPConnector(verify_ssl=False)) as session:
text = await fetch_all(session, urls, httpc_params)
return text

Got the point,

you can do that overloading this variable HTTPC_PARAMS in the general settings (settings.py of your project, without chaning application source code)
