Redpanda should properly decode path parameters vs query parameters #16129
Description
Version & Environment
Redpanda version: (use rpk version): all versions
What went wrong?
The + symbol is being improperly decoded to become a space character when it's found in a path parameter when path parameters are decoded using seastar's url decode method.
What should have happened instead?
Replacing a + with a space is valid for query parameters, but not path parameters. A + in the path should be left as is.
Need to create a path_decode method to be called specifically for path parameters.
