Add a way for search to filter on notes txstate-etc/reqquest-txstate#253

[chastabor]

• Added note content as part of search
• Restricted filter for reviewer only. NOTE we may want more fine grain where anyone that can view notes can search on them.
• Modified notes to utilize mysql text indexing. A few considerations:
  • Text indexing mysql feature has been available before our imdb version of 5.7.44-48-log
  • Decided to not use boolean features but rather only full text as boolean notation does not match what other search fields are using.
  • We are using LIKE % in other search locations; so this will be different, however, matches how a user would expect to search note content.
• Added reviewer and applicant testing for note search and verified potential new results did not break existing tests.
