Description of problem:

When adding a config server to a provider account in Conductor, the hostname, key, and secret values are not trimmed on submit.  As a result, trailing (unseen) spaces in either of those fields results in a 401 error (or, potentially a 404 error, if the hostname field is the one with an extra space) when Conductor tries to authenticate against the config server with untrimmed values.

Steps to Reproduce:
1. In conductor, add a config server to a provider account
2. Enter a valid hostname, consumer key, and consumer secret in the text fields
3. Add an additional space at the end of the consumer key field
4. Click "Save"
  
Actual results:

Conductor reports that it cannot add the config server, because it received a 401 when attempting to authenticate.


Expected results:

Conductor should automatically trim the input values before saving and testing the connection to the config server.
