Investigate downloading binaries (instead of including) & reusing existing ones on the path

[adietish]

we currently include binaries in the extension. We should look into downloading them at runtime and maybe even use binaries that exist on the path.

Might be worth looking back on #1227 , #10 . Is the goal here to reduce the extension size ? Or do you want a given release to be usable without having to upgrade (to one that has the proper embedded version). If so, is there evidence that users aren't mainly just upgrading to latest release ?

@rgrunber Yet another issue to target here is #4535 - Che Workstation is running on RHEL 8 and has GLIBC v 2.88 installed that prevents the most recent versions of some bundled binaries (oc, odo, alizer) from being executed as they require GLIBC v.2.32+/v2.34+ to be installed.
Allowing the use of preinstalled binaries (search in user PATH) or manual installation of the required CLI binaries could help.

On LemMinX, we ship a separate (static) binary for distros that don't have glibc. Is that an option here ? Have a static version of the binaries that would work ? Otherwise, yeah downloading some older version is one way around it.
