feat(env): setSpecProperty/setSuiteProperty(key, value) to attach data to tests

Use setSpecProperty to attach key/value pairs to spec results that can be
picked up in specialized jasmine reporters.  Example use-cases
include:
  * Tagging specs with URLs or string-tokens referencing test-plan docs.
  * Recording performance information for blocks of JS.
Similarly setSuiteProperty attaches key/value pairs to suite results
