true non root install phase 1

The non root install currently requires that you enable passwordless sudo access for the account which is not as desirable. For an initial phase of improvement here, we should allow all normal ongoing operational use cases (query, dml, cpimport, shutdown, startup, etc) to work with no sudo access. Installation and system mainteance tasks such as addModule could still depend on sudo access but the more we can simplify the better.

After initial review, the decision was made to move towards a model where we more mirror the core mariadb server which will be needed for convergence anyways:

• Move away from the dedicated split of root and non root installs.
• Officially support only os package installs (i.e. rpm deb).
• Binary install will still be needed unofficially for dev setups or supporting non standard linux distros.
• The os package install should install the columnstore components and run under the mysql user (like server).
• Any required root steps then can be done as package scripts which are run as root.
• Migration paths will need to be developed / tested for upgrade.
