apihost name does not tolerate trailing slash

[rabbah]

Describe the bug
Similar to the issue reported here apache/openwhisk-cli#481, a trailing / on the API host also causes a failure in aio.

To Reproduce

> ./bin/run runtime:action:list --apihost https://example.com/
 ›   Error: failed to list the actions: 404 Not Found
 ›     specify --verbose flag for more information

With the --verbose setting:

  aio-cli-plugin-runtime OpenWhiskError: GET https://example.com//api/v1/namespaces/_/actions Returned HTTP 404 (Not Found) --> "Response Missing Error Message."

Expected behavior
A trailing slash should be ignored.
