Make verify_peer configurable and default it to false

[aharbick]

Resolves #293

Also note that this doesn't make these warnings

[WARNING; em-http-request] TLS hostname validation is disabled (use 'tls: {verify_peer: true}'), see CVE-2020-13482 and https://github.com/igrigorik/em-http-request/issues/339 for details

go away unless this is merged: igrigorik/em-http-request#341

OR verify_peer: true is used.

Thanks for the contribution! Can you add this new option to the README too?

[aharbick]

How about 356cbc1 @ronwsmith ?

[ronwsmith]

Looks good, will try to get this in soon!

@ronwsmith Would you be able to merge this? It would really help to reduce the noise in our logs

@CarwynNelson thanks for the nudge, just released in 2.4.0
