Repository properties

I have to work with some Maven projects using Maven remote repositories with no Maven index (either Nexus without indexing enabled or simple DAV repositories). NetBeans tries to index such remote repository despite the index is not present and the indexing never stops → any functionality which relies on indexing shows that indexing is still in progress (e.g. autocomplete in POM file, see the attached screenshot).

There are also produced files like 'nexus-maven-repository-index.properties1230112283458172920' with zero size in user TEMP directory which are never deleted (files created by indexing of an existing index are deleted). NB 8.0.1 constantly produces hundreds of files per minute (!) which is not too good for my SSD. This was partially fixed in #246409, so the latest dev. build produces only few files (one for each repository?) only for index-depending action like autocomplete in POM, but files are still not deleted.

In the repository properties dialog, there is a "Remote Index Downloadable" checkbox which is selected, but disabled. Maybe it's another bug, or is it just prepared for functionality which was not implemented yet?

Summary of requirements:
- stop the indexing process when index is not available, or:
- allow possibility to disable downloading the index/indexing of specific repo - a workaround like configuration files tuning would be fully suitable for me, but enabling the "Remote Index Downloadable" checkbox to allow to deselect it would be very nice,
- delete temporary files created for repo with no index.
