Add .deb and .rpm Installation and make .tar Installation the Fallback

[Jostrus]

Description

These changes switch to an installation via .deb or .rpm depending on the underlying operating system and use the installation from the tar bundle as a fallback. In addition, the installation and configuration have been split into two different YAML files and variables have been added for the RedHat and Debian operating systems

I think there was a discussion on switching to rpm but stopped. In ODFE we used to use rpm tho I think. cc @saravanan30erd into the conversation on this. Thanks.

Hi @peterzhuamazon, thanks for reviewing my PR. I understand if the decision was made not to install OpenSearch via .rpm or .deb package. If you prefer, I can rewrite my changes and make the tar install the default, and only if for example the os_repository variable is set to true it should be installed from the repository. I still want to give the possibility to install from a package, because in this case OpenSearch is listed in the package manager database.

Hi @Jostrus , It would be great to have different distribution options and I do agree with that. My concern is whether this would make the playbook hard to maintain over time. In helm due to its relationship with k8s and docker containers, contributions will be focused only on one distribution, unlike ansible playbook you can add multiple.

Will wait for more comments from @saravanan30erd and @prudhvigodithi on this. Thanks.

My concern is whether this would make the playbook hard to maintain over time.

I completely agree with @peterzhuamazon on this point. Previously we had discussions about using .rpm, .deb packages for installation but opted out. Current installation is distro agnostic and pretty much supports most of the linux distributions. One example is, Initially we created and tested this playbook against RHEL7, Centos7 but it still works for recent releases like RHEL9 literally without any specific code changes. Adding multiple methods (specific to particular distros) for installation would make difficult to maintain over time.

Hey @peterzhuamazon and @saravanan30erd, If that's better, I can rewrite my changes to only do the .deb and .rpm installs if the user explicitly selects that and default to the .tar install. I like distribution dependent installs for many reasons, so I will contribute to this repositroy as best I can. If you still say no because it would be an unnecessary overhead, which I completely understand and sympathize with, I will respect that decision and close this PR.
