[Fiware-tech-help] [Chp - IoT][IDAS] Specify the user who must execute the commands

[David Muriel]

There are no specific information about what user must execute the
commands needed during the platform install process.  Some sections of
the installation guide have references to using "su -" or "sudo" while
others don't have any information regarding the user that must execute
the commands.  As the majority of the commands should be run by root,
it is better to specify this information at the begining of the guide
with something like:

    Unless otherwise stated all commands must be run as root.

Then, specify the user to run the commands only when it is not root.
