UI for Java script N1QL UDF support

For N1QL JS UDFS we typically have to do the following:

1. Register a library, having all relevant functions, with the evaluator. This can be done by POSTing the library code to the “evaluator/v1/libraries” REST endpoint.

2. A N1QL function now needs to be registered against the function you want to execute.

 The 1st step is done via curl and 2nd step can be done via QWB.

If we could find a way to do step1 in UI as well, that would be perfect.

For e.g.

1.

curl -v -X POST http://localhost:8093/evaluator/v1/libraries/udf2 -u Administrator:password  -H 'content-type: application/json' -d 'function queryselect(){var a = 10;var query = INSERT INTO b values(UUID(),

) returning meta(), *;var acc = [];for (const row of query)

return acc;}'

2.CREATE FUNCTION qs4() LANGUAGE javascript AS "queryselect" AT "udf2"      

3. EXECUTE FUNCTION qs4()

Step1 happens via curl on command line
Step 2 and 3 can be done via cbq or QWB
