raft: grow the inflights buffer instead of preallocating
...
Grow the inflights buffer as needed instead of preallocating it to its
max size. This avoids preallocating a lot of unnecessary
space (8*MaxInflightMsgs) when using lots of raft groups while still
allowing for a reasonable MaxInflightMsgs configuration.

raft: use a singleton global rand
...
rand.NewSource creates a 4872 byte object. With a small number of raft
groups in a process this isn't a problem. With 10k raft groups we'd use
46MB for these random sources. The only usage is in
raft.resetRandomizedElectionTimeout which isn't performance critical.
Fixes #6347 .

raft: Allow an election immediately after start with checkQuorum
...
Previously, the checkQuorum flag required an election timeout to
expire before a node could cast its first vote. This change permits
the node to cast a vote at any time when the leader is not known,
including immediately after startup.

raftpb: atomic access alignment
...
The Entry struct has misaligned fields that are accessed atomically. The
misalignment is caused by the EntryType enum which the Protocol Buffers
spec forces to be a 32bit int.
Moving the order of the fields without renumbering them in the .proto file
seems to align the go structure without changing the wire format.

The relevant structures are properly aligned, however, there is no comment
highlighting the need to keep it aligned as is present elsewhere in the
codebase.
Adding note to keep alignment, in line with similar comments in the codebase.
