Add support for individual observation tagging #345
Description
Describe the feature you'd like and what it will do
HydroServer's thing and datastream tagging functionality would be extended to allow tagging of individual observations. This feature would replace existing result qualifier functionality, and result qualifiers would be converted to tags with the key "ResultQualifier", and value equal to the result qualifier code. Result qualifier descriptions would be dropped.
Why is this feature important?
Tagging allows greater flexibility for attaching metadata to observations than result qualifiers. While result qualifiers are more controlled, they limit users ability to tag observations with unique metadata.
Tagging would likely be slightly more performant than result qualifiers because tags do not require a join table while result qualifiers do.
