Alpine as base image

Using Alpine as base image for Apache Solr docker images to reduce vulnerabilities

[dsmiley]

I didn't do a diff but are these duplicating the existing ones except for the FROM? It's a maintenance burden to support such code duplication.

[manideepgoudparuchuri]

This is not the duplication of other codes. I have changed FROM to use alpine as base image and **changed commands which installs packages ** while it starts building the image.

In other codes we used ubuntu image which uses apt package manager and now in alpine we use apk package manager for installing packages inside image.

If we are to support alpine - and I think that should be first decided on the dev list - the change will need to go not in this repo but in the main solr repo in the templating, so that the docker file is auto generated for each solr build.

Please start a dev list thread with your proposal.
For background, we used to publish an alpine image years ago but ditched it for ease of maintenance, and also the current Debian base images are much slimmer than they used to be.
