Let's have a single branch which can compile on most Centreon versions, instead
of maintaining a new branch for each version.

fix(doc): Most of this has been published on doc.canopsis.net

See merge request !7

85-amqp.so for centreon 19.04

So, avoid duplicating information here.

Asked by @mmourcia.

Update include line 31 and 36.
Update test line 1643.

For CentOS 7, a vanilla CentOS install can be used, but for CentOS 6 you need
CES's version, because they need an updated Qt.

Just disable the Lua dependency, which we don't need.

* "$HOME" instead of "~", because Boost doesn't know how to expand "~", and
  blindly uses it as a raw character.

* Use a dedicated sub-directory, to avoid polluting any user home.

* Translate it to French by default.

* Always build it with a static Boost library, since using the system library
  makes it prone to break during system upgrades.  This is what we have been
  doing for a while.

* Don't repeat (a different version of) the installation process, which is
  already available in README.md.  Just document the build process, here.

* Avoid an unnecessary dependency on unzip.  Also switch Boost sources to
  .tar.bz2 sources, which are smaller.

* Avoid doing a "git reset --hard" in the middle of the process, in case
  you had some precious staging work.

* Reorder and simplify things.

* Explain that this connector plugs inside Centreon and sends data to Canopsis.

* Add a warning to make sure that data transmission is allowed on the network
  between Centreon and Canopsis.

* Add a warning to make it explicit that the "Restart" option in Centreon will
  stop the service for a brief moment.
