Create HCA Login

[Bento007]

As a user of the HCA CLI, I would like to login into the CLI in a intuitive way, so I may use service that require authentication.

Defintion of Done

• Remove hca dss login
• Remove hca query login
• Use a single token for all authenticated request in the hca
• add hca login
• add hca login --refresh-token to login and generate a refresh token.
• add hca revoke to revoke the current refresh token.

Heads up to @kozbo and @kislyuk that these changes will affect your cli commands.

Using the revoke endpoint in auth0 will revoke all refresh tokens give to that user by auth0 not just the one provide in the request. We should make a complete logout optional.

def logout(revoke=False)
    """ Logout the user, if revoke is true, all refresh tokens issues 
         to that user for the hca will be revoked."""
    pass

We should also make it clear when logging in that a refresh token is not required and should only be used on secure machines.

depends on #417

Can we return an error message from hca dss login telling the user to use hca login?
