1. jobs: fix bug in WriteChunkedFileToJobInfo during overwriting …

   Previously, `WriteChunkedFileToJobInfo` would chunk up the
   passed in byte slice and write the chunks to the job_info table
   with info keys constructed using the filename. If the method
   were to be invoked again with the same filename, due to the
   delete before write semantics of the job info table, if the
   number of chunks changed then we'd end up with a corrupt
   file. With chunks from the first and second write mixed.
   
   This change fixes the bug by first deleting all the chunks that
   correspond to the filename before writing the new data. This
   is in line with how you'd expect an overwrite operation to
   work. This change also adds a regression test for the same.
   
   Fixes: #113232
   Release note (bug fix): fixes a bug in a method that was used
   by some of the jobs observability infrastructure, that could be
   triggered if a file was overwrriten with a different chunking
   strategy
