Remove SSL warnings when not veryfing certs

[maaaaz]

Hello @taraslayshchuk,

By default, certs are not verified and a lot of warnings are displayed and spam the console.

Could you just print at the beginning of the execution a simple warning like "[!] certs are not verified, use --verify-certs instead" and disable original warnings with the directive like urllib3.disable_warnings()

Cheers !

@maaaaz I had a similar problem and sudo pip install certifi.

Since the library is using urllib3, the main workaround is to use pyopenssl when available.

To do this, add this to the beginning of the code:

try:
  import urllib3.contrib.pyopenssl
  urllib3.contrib.pyopenssl.inject_into_urllib3()
except ImportError:
  pass

This will allow interested parties to pip install urllib3[secure] in addition to es2csv and ensure they can validate certificates.
