feat(cli): add option to skip tls verification or define ca certificate

[nwsparks]

Is your feature request related to a problem? Please describe.

We have to operate behind an outbound proxy that does ssl inspection. When executing from the container we receive the following error since the proxy CA certs are not available inside of it.

WRN Unable to get descriptions: Get "https://kics.io/api/": tls: failed to verify certificate: x509: certificate signed by unknown authority

Describe the solution you'd like

Ideally a flag such as --skip-tls-verify

Describe alternatives you've considered

I've tried the golang env variables without luck

GOINSECURE=kics.io
GO_TLS_VERIFY=0

Another option would be to rebuild the container you provide with our ca certs loaded but that is cumbersome.
