Update README for "Heketi Admin and User Keys required" error

[ChanderG]

Is easily resolved by updating the command:

./gk-deploy -g --admin-key <key> --user-key <key>

The README instructions should be updated.

Which keys are these? Is this the file name of an id-rsa file? Is this the resource name for a kubernetes Secret? Is this some random string that will be used as a password?

[ChanderG]

From what I recall, random strings to be used as passwords.

I tried with random strings it didt work. And if I looked at the gk-deploy script, user key is not mandatory. Can you shed a light here?

Edited: I used 'admin' as the admin key (not sure if this is considered random) and ignored user key. It worked!!
