First attempt to add ergocub sw documentation

[martinaxgloria]

Since #282, I'd like to add a new section within icub-tech documentation that would be specific for ergocub software (like for icub hw and icub sw). My idea is to document the installation of both ergocub-head and ergocub-torso and the specific procedures and modules for each of them (e.g. librealsense installation for ergocub-head), the ergocub network specs (made by @davidelasagna) and other stuff that are not completely linked to icub documentation.

In this PR, I proposed a potential new layout with some sections already filled in thanks to @davidelasagna.

Hi @pattacini,

I got the point. I'll remove the major section I've created and I'll move the pages under the iCub software section

Hi @pattacini,

As you proposed, I made some changes here https://github.com/icub-tech-iit/documentation/pull/318/commits/009b1e630e0462c2385465dcc5a757aa16624222

With https://github.com/icub-tech-iit/documentation/pull/318/commits/b6f060ee5e369c134c80ef259ccf7a4be4f8f265, I added other pieces of documentation and the references to the existing pages with the specs for ergocub.

Hi @martinaxgloria

There are conflicting files needing your care.

I did it myself.

Some other quick suggested inline amendments.

Done!
