Add support for includes in SSH profile generator

Description of the new feature

SSH profile generator currently doesn't seems to support includes so:

.ssh/config:
Include config.d/*

.ssh/config.d/:
config1
config2
config3

result in no profile being generated.

I do think it is a common was to structure profiles, especially when having many, would be nice for it to work in terminal.

Proposed technical implementation details
