588f655b4e etcdmain: add an option for pprof 
This commit adds a new option for activating profiling based on pprof
in etcd process.
 - -enable-pprof: boolean type option which activates profiling

For example, if a client URL is http://localhost:12379, users and
developers access heap profiler with this URL:
http://localhost:12379/debug/pprof/heap

d9ca929a33 *: add support for lease create and revoke 
Basic support for lease operations like create and revoke.
We still need to:
1. attach keys to leases in KV implmentation if lease field is set
2. leader periodically removes expired leases
3. leader serves keepAlive requests and follower forwards keepAlive
requests to leader.

1714290f4e storage: support recovering from backend 
We want the KV to support recovering from backend to avoid
additional pointer swap. Or we have to do coordination between
etcdserver and API layer, since API layer might have access to
kv pointer and use a closed kv.

384cc76299 pkg/testutil: make Recorder an interface

like the original version and one that provides a blocking channel
to avoid busy waiting or racing in tests when no other synchronization
is available.

ee0b3f42ed *: rename watcher to watchStream 
Watcher vs Watching in storage pkg is confusing. Watcher should be named
as watchStream since it contains a channel as stream to send out events.
Then we can rename watching to watcher, which actually watches on a key
and send watched events through watchStream.

This commits renames watcher to watchStram.

aef55342d1 etcdsever: avoid creating member dir before finishing validate bootstrap 
This commit fixes the issue of creating member dir before validating
the configuration. When member dir exists, it indicates the local etcd
process is a valid etcd member. So we should only create member dir
after we finish configuration validation, joining validation or
discovery validation.
