Erlang OTP 26 ssl defaults

[tzirechnoy]

OTP 26 changed the default verify option value in the ssl:connect from verify_none to verify_peer: https://www.erlang.org/blog/otp-26-highlights/#ssl-safer-defaults

This breaks most of the tsung SSL client code.

The final error looks like:

** Reason for termination ==
** {badarg,[{erlang,atom_to_list,
                    [{options,incompatible,
                              [{verify,verify_peer},{cacerts,undefined}]}],
                    [{error_info,#{module => erl_erts_errors}}]},
            {ts_client,reconnect,5,
                       [{file,"src/tsung/ts_client.erl"},{line,1057}]},
            {ts_client,handle_next_request,2,
                       [{file,"src/tsung/ts_client.erl"},{line,834}]},
            {gen_fsm,handle_msg,8,[{file,"gen_fsm.erl"},{line,475}]},
            {proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,241}]}]}

Here is a quick and dirty patch, to possibly fix the issue:

I have same problem.

[RomaniukVadim]

Same problem here, but i think it will be better to add option like <set_option name="ssl_verify" value="verify_none"/> Forcing verify_none is bad, but user should have option to disable this verification.
