conan package manager support

[Ri0n]

Instead of making custom SDK it would be great to use ready to use binary packages. Conan has them for various platforms and compilers. OpenSSL for example is there already.

Conan has documentation how to make own binary packages and keep them for free on 3rdparty storage services. Moreover even building will be done in cloud.

So we have to add packages for qca and its deps to make basic support working. I've already start deps for cysrus-sasl qca plugin.
