Update the Schema used by Dashbuilder Editor for auto complete and validation:

• Remove lower and capitalized cases from enums, keep only upper case alternatives:

• Add the new/missing fields in the schema:

• • dataset: Global new dataset declaration. Should support all dataset fields.
  • allowUrlProperties: when true then properties can be replaced using URL query parameters. It is a global parameter.
  • settings <-> displayer: settings can also be displayer now
  • Datasets missing fields: accumulate (boolean), maxCacheRows (number), headers (a map), join (an array) *  and *query (a map)
  • New functions for grouping:
    • MEDIAN, JOIN, JOIN_COMMA, JOIN_HYPHEN
  • Missing group function: COUNT
• Remove enabled  from filter as a mandatory field
• New string components:
  • screen: {pagename}   - to embed a new page. It is a top level component, such as html
  • panel: {pagename}   - to embed a new page with a titled panel. It is a top level component, such as html
  • markdown: {content}   - to create markdown content. It is a top level component, such as html
• new displayer type: TIMESERIES
• The type for column in dataset.columns is not required anymore. By default all columns are of type LABEL.
