CB-13978: Show a warning when cbd looks up Profiles from the PATH.

[brycederriso]

Closes CB-13978.

Made a mistake, still testing this.

Ganesh pointed out that this doesn't gracefully deal with . in the $PATH.

Further, I'm getting errors when running this locally:

 cbd start

An example of the output:

$ cbd ps
[WARN] Multiple Profiles found on your path will be used, this might not be desirable: /Users/brycederriso/bin/Profile
      Name                     Command               State                    Ports

It's not perfect, but at least gives a warning.
