ArangoSearch refactor

HTTP docs:

• there is no attribute "properties": { ... } expected, but rather the View properties directly (same level as name and type). This needs to be fixed (pointed out by Vadim).
• there are multiple places where the response object is described, but without code and error
• result is not mentioned / described as containing the important query result
• globallyUniqueId is not mentioned and missing a description - it's an internal attribute as per Vadim, which collections have as well.
• response structure only described in text, not for in Swagger way
• immutable View properties:
  • globallyUniqueId
  • id
  • primarySort
  • type (?)
  • writebufferActive
  • writebufferIdle
  • writebufferSizeMax
• make links from Java driver to ArangoSearch/Views HTTP docs more specific again? They used to link to e.g. views-getting.md, which I removed in the main repo PR because it's basically useless and redundant as long as we don't have any other View types.
• broken hierarchy https://deploy-preview-89--zealous-morse-14392b.netlify.com/docs/3.5/http/views-arangosearch.html, probably Sub-objects at depth 3+ missing in HTTP response description #106
• 3.5\arangosearch-analyzers.md#analyzer-features:
  • For example the text type will produce <!-- supports? -->
  • norm: the field normalization factor <!-- effect? -->
  • <!-- what else requires which features? -->
