Add support for SL4j logging for Solr versions >= 4.3
Use root user to copy jars. Use current, rather than default, node solr version for split version
comments
Dont check for default attribute for sl4j
Add solr.xml to cookbook files. Copy solr.xml into solr home if its missing.
Fix cookbook_file
Add log4j property template. For solr > 4.3, add log4l property file into jetty resource directory. Refactor and revise attributes.
Refactor. sl4j / log4j has recipe
Fix conditional for including sl4j recipe
remove sl4j recipe. Just use default. Rename attributes. Explicitly restart jetty at end of recipe.
Dont set solr.xml by default. Let application handle it
Log4j appender should be in resources folder, NOT resource folder.
