Make apt-get calls consistent

[Flamefire]

• Don't install packages implicitely
• Make quiet(er)
• Use retries

@sdarwin I've seen some Boost repos already using this, so I figured it makes sense to make it universally used. Can you see any potential issues with this?

ci/codecov.sh is being used by:

• CI jobs to run codecov
• Customized lcov reports

I am not certain if the modifications "--no-install-suggests --no-install-recommends" will affect those jobs. In terms of customized lcov/gcovr jobs, those scripts are also installing Perl packages, which means it wouldn't be problematic to adjust those scripts to proactively install 'recommends' and 'suggests' if necessary.
As far as codecov itself, if you have tested it in boost-ci and that is still working, OK.

see other comments. Should be alright.
