To the reviewer
This PR is another iteration on this ticket, so it's probably not the final one. However, the number of changes is significant, so I prefer to submit it for review now.

Are you sure that we don't need it anymore? I remember there were issue with PostgreSQL. I hope it won't affect upgrade from PMM 2 to PMM 3.

Yes, pretty sure. From the logs, the OS emits a good number of warnings not being able to apply just LC_ALL. However, once the language package is installed, we see that the default OS language settings are set, as expected, to en_US.utf8. Therefore, this removal fixes the the warnings related to things that don't work anyway.

To give us a bit more comfort going forward with this removal, this is what the output of locale currently looks like (i.e. before this removal):

LANG=en_US.utf8
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=

As you can see, LC_ALL is empty for the reason mentioned above. Thus, it's no harm.
