This commit updates the docs for the config files to explain the new
mechanism for customizing the configuration directory via the
environment variable CONF_DIR.

#9261 added a warning about the use of `add-apt-repository` which is becoming obsolete over time as new distribution releases include later versions of `add-apt-repository` which don't automatically add the `deb-src` line. This change updates the documentation to make the block a note rather than a warning and adds two other reasons for avoiding `add-apt-repository` which are still relevant: avoiding edits to a system shared file and not requiring a large number of non-default packages to add one line of text to a file.
During package install on systemd-based systems, we try to set
vm.max_map_count. On some systems (e.g., containers), users do not have
the ability to tune these parameters from within the container. This
commit provides an option for these users to skip setting such kernel
parameters.

With the unified release process across the elastic stack, download
links for all products are changing. This change updates docs referring
to the old download and packages urls.
Note that this change also updates the plugin installation command as
the url for downloads is being changed to be consistent with that for
packages (both plural).
This commit removes the ability to specify a custom plugins
path. Instead, the plugins path will always be a subdirectory called
"plugins" off of the home directory.
