Add option to not validate certificates to Inso

[smgoss]

As a developer of a server product I regularly build and testing using self signed certificates which by default are not trusted by most everything.

I would like a way to tell Inso not to validate the certificates similar to Validate certificates checkbox under the Request/Response section of Insomnia. Either as an environment flag, config file, or command line switch.

The unit tests I build in Insomnia work great and I would love to use them in a pipeline but we expect our customers to install their own trusted certificate for our application so we do not ship with one and the default that it uses is a self signed certificate. For me to use Inso in a pipeline it must allow self signed certificates in some way.
