What does this PR do? What is the motivation?
Documents a new Synthetic Monitoring capability: use-site variable filters. When you reference a variable in a test, you can now pipe its resolved value through a filter to transform it before it is injected into the request — for example
{{ TOKEN | urlEncode }}.Four filters are supported:
urlEncode,urlDecode,base64Encode, andbase64Decode. They work for both local and global variables and across all test types, which is why the docs live in the sharedsynthetics-variablesshortcode (included by the HTTP, multistep, browser, mobile, gRPC, SSL, TCP, UDP, WebSocket, DNS, and ICMP test pages).Merge readiness
