Optionally disable ssl checks in all client requests

[julien-nc]

closes #988

Can be useful when using self signed certs for the IdP.

Isn't it feasible to just import the self signed ca into the certificate chain? That way you could still validate the certificate

Similar to what we do in integration_openproject. import the certs in development environment to be able to use self-signed certs.
See https://github.com/nextcloud/integration_openproject/tree/master/dev

Sure it's possible to import a cert in NC or to add it to the system certs. I thought it could be convenient to quickly and temporarily disable this check for people who want to quickly setup a test environment.

@juliusknorr So you think this PR is not necessary and we should close it?

[juliusknorr]

I'm fine either way, we have this kind of setting in a lot of places in Nextcloud.

Any updates? It's been inactive for months.

Thank you.
