As discussed in #200, this PR adds the ability to override the security level used by OpenSSL. This allows for still using cipher suites like TLS_PSK_WITH_AES_128_CCM_8 that must be supported by CoAP implementations (see section 9.1.3.1 of RFC 7252), as more recent versions of OpenSSL are not allowing them to be used anymore without lowering the security level.

The DTLS example is adjusted accordingly so that it now works again.
