This commit expands RPCs for getting user and role and support list up
all users and roles. etcdctl v3 is now support getting all users and
roles with the newly added option --all e.g. etcdctl user get --all
Currently auth tokens are generated in the replicated state machine
layer randomly. It means one auth token generated in node A cannot be
used for node B. It is problematic for load balancing and fail
over. This commit moves the token generation logic from the state
machine to API layer (before raft) and let all nodes share a single
token.
Log index of Raft is also added to a token for ensuring uniqueness of
the token and detecting activation of the token in the cluster (some
nodes can receive the token before generating and installing the token
in its state machine).
This commit also lets authStore have simple token related things. It
is required because of unit test. The test requires cleaning of the
state of the simple token things after one test (succeeding test can
create duplicated token and it causes panic).
There was a bug in protodoc.
This changes git SHA to use the latest protodoc.
And make the letter casing consistent with original
Protocol Buffer. Go capitalizes the member variables,
but the protocol buffer documentation should be same as
original proto files.
