Closes #246. This pull request extends the YAML parser API to include:

/// \brief Parse a parameter value as a YAML string, updating params_st accordingly
/// \param[in] node_name is the name of the node to which the parameter belongs
/// \param[in] param_name is the name of the parameter whose value will be parsed
/// \param[in] yaml_value is the parameter value as a YAML string to be parsed
/// \param[inout] params_st points to the parameter struct
/// \return true on success and false on failure
RCL_YAML_PARAM_PARSER_PUBLIC
bool rcl_parse_yaml_value(
  const char * node_name,
  const char * param_name,
  const char * yaml_value,
  rcl_params_t * params_st);

This way, parameter addressing information can directly provided along with the parameter value as a YAML string to be parsed.

Depends on #470.

LGTM. Left a few comments below.
I would do a "rebase and merge" to keep the rcl dependency removal in a separate commit from the new function.

Ah, nevermind, I see #470 🙃

@jacobperron had to rebase after changes got applied to #470, sorry about that. PTAL.

If we use ASSERT_*, I think we should make sure to free resources in the event that the assertion fails. We can use the helper OSRF_TESTING_TOOLS_CPP_SCOPE_EXIT to make sure test_path, path, and params_hdl are cleaned up when the test exits.

I guess this should also be added to the other tests as needed.

I thought about it, but since it's a test I was less worried about memory freeing. But using OSRF_TESTING_TOOLS_CPP_SCOPE_EXIT sounds like a much better plan.

Previously, some folks went through and fixed a bunch of leaks detected by ASan jobs (for example). Even though they're just tests, it will make those jobs happy.
