check_crls: false in receiver config - investigate if this should be true

[tofu-rocketry]

It sets crl_check_all as an argument for openssl. Does this end up checking every cert in the chain?

Needs testing.

-crl_check_all
Checks the validity of all certificates in the chain by attempting to look up valid CRLs.

Yes, it does. We can add/replace it with the option of just -crl_check to only check the first certificate.
