Consider removing insecure getTlsSslContext and trustAllCertificates

[intrigus-lgtm]

Issue Overview

Hi, please consider removing trustAllCertificates and
getTlsSslContext.
Both are not used by arquilian-cube as far as my static analysis tool knows.
Both functions are in my opinion dangerous and should be removed if they are unused.
trustAllCertificates trusts all certificates and disables hostname verification.
This is problematic, because it does this for every HttpsURLConnection.
getTlsSslContext only trusts all certificates but does not do this for every HttpsURLConnection.

Obviously this is your project so there might be very valid reasons to keep these methods :)
