Check_MK Werk 7389: check_http: Enable SSL/TLS hostname extension support by default

ID: 7389 Title: check_http: Enable SSL/TLS hostname extension support by default Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 Previously users had to {enable SSL/TLS hostname extension support} (SNI) explicitly. Omiting the option could result in unexpectedly checking different content/certificates than the {host address} option would suggest. We now assume users want SNI support. Users that relied on the previous behaviour of disabled SNI can disable SNI explicitly useing the option {Advanced: Disable SSL/TLS hostname extension support (SNI)}.
