REORG: ssl: move ssl_sock_ctx and fix cross-dependencies issues

In order to move all SSL sample fetches in another file, moving the
ssl_sock_ctx definition in a .h file is required.

Unfortunately it became a cross dependencies hell to solve, because of
the struct wait_event field, so <types/connection.h> is needed which
created other problems.
