Unattended installer - Second iteration with improvements

[alberpilot]

After tagging the unified-unattended installer, we will move forward for including some improvements described in the following issues:

• The unattended installer should be released as a single artifact. All modules (libraries, resources, templates) must be joined into the mentioned artifact. The unattended installer development doesn't change, but a new tool for this artifact building must be created.
• All module functions must start with the name module prefix. (i.e. indexer_configureCertificates).
• All distributed messages must be reviewed, guiding the user to an unattended installation. Those messages must have links to documentation but, in addition to this, must be self-explained and could avoid the users going to the documentation for checking.
• Error messages must explain what is happening and links to the documentation, dependencies/requirement section.
• The unattended installer must detect the OS and check if it's compatible. Links to documentation are needed.
• Improve the error handling including set -Eeuxo pipefail, using traps, and including more fail information, like line number, error code, etc. (reference)
• Use printf instead of echo.
• Functions must return true or error code.
• Don't assume terminal capabilities. Check if $TERM is set as unknown, untested, or whatever. Don't use control codes like scape chars, tputs, etc.
