title: Renaming hundreds of Kusto table columns in one shot
body: <p>My query returns a bunch of columns that I can't manually rename (using <code>project-rename</code>) one by one. Also the input query is fixed , I can't change it and it may return different number of columns each time I run it, so I can't have a fixed <code>project-rename</code> statement. For example lets say for one of the runs of the input query the result is the following columns:-</p>
  <pre><code>fixedstring_region
  fixedstring_state
  fixedstring_level
  fixedstring_reach
  fixedstring_mode
  fixedstring_something
  fixedstring_otherthing
  ... etc
  </code></pre>
  <p>These can be hundreds. I want to remove 'fixedstring_' from all of these. Is there some wild card technique for this?</p>
