In elastic/elasticsearch#1442 checkstyle checks were added, but also some files were freed from this.
If we have support for checkstyle, we should check this for all files and not allow
exceptions. This commit removes the file list to ignore any files and fixes all the
java files.

If elasticsearch merges https://github.com/elastic/elasticsearch/pull/16413
then the build will fail catastrophically without this. The goal here is to
opt these files out of the line length checks while they don't pass and we
can get them passing as time permits and opt them back in. In the mean time
all files that pass the line length check will have the check enforced.
This also gives you a spot to add x-plugins opt outs for core's checkstyle
rules in case you have generated files or something like that.
