Changed Dockerfile to resolve version conflict for libapt-pkg5.0

[leinenk]

When trying to build a dockerimage for CDAP 6.10.1, I received following error during the build process:

The following packages have unmet dependencies:
dpkg : Breaks: libapt-pkg5.0 (< 1.7~b) but 1.4.11 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

I was able to solve the problem with the adjustments I made to the Dockerfile. The main changes are in the build stage where I've:

• Removed the problematic NodeSource repository setup
• Added the n version manager installation
• Installed Node.js 10.24.1 using n
