exec credential provider: add install hint

Browse Source 
This commit adds the ability for users to specify an install hint for
their exec credential provider binary.

In the exec credential provider workflow, if the exec credential binary
does not exist, then the user will see some sort of ugly

  exec: exec: "does-not-exist": executable file not found in $PATH

error message.  If some user downloads a kubeconfig from somewhere, they
may not know that kubectl is trying to use a binary to obtain
credentials to auth to the API, and scratch their head when they see
this error message.  Furthermore, even if a user does know that their
kubeconfig is trying to run a binary, they might not know how to obtain
the binary.  This install hint seeks to ease the above 2 user pains.
