Added the actual read hot detection algorithm and logging machanism.
...
- When a shard has a read bandwidth larger than a threshold value(configurable via knob), and it's read-bandwidth/byte-size ratio is also larger than a threshold(configurable via knob), the corresponding shard tracker will run the algorithm
- The algorithm will divide the shard into 10MB(configurable via knob) chunks and try to find the chunk(s) that has large aforementioned ratio
- Then those ranges will be logged into TraceEvents. This will later do more like actually cache them.

Make a smaller range inaccessable after writing a versionstamped key
...
A transaction's read version is the lower bound of what a transaction's
commit version could be. Thus, we can narrow the conflict range of a
versionstamped key, and thus reduce the amount of the keyspace that is
rendered inaccessable, by filling in the read version on the
versionstamped key and using that as the lower bound of the conflict
range.
This allows reads to still be done to versionstampled keys lower than
the read version of the current transaction.

Monitor leader only when proxies are unknown or any dies

FDB clients talk to coordinators to monitor the leader, and then ask
them for proxies. Once proxies are known, the clients still keep
talking to coordinators. This patch, stops this monitoring and
reconnects to coordinators only if one of the proxy is no longer
available.

Allow to turn on object serializer
...
This commit includes functionality to turn on
the object serializer for network communication.
This is done the following way:
- On incoming connections, a process will detect
whether the client supports the object serializer
and will only serialize responses with it, if it does
- On outgoing connections, the command line flag is used
to determine whether the object serializer should be used
to send data.
This way, a cluster can run in mixed mode. To upgrade one
can upgrade one process at a time and set the flag one process
at a time.
This is how this is tested on the simulator:
- The command line flag can take three options: on, off,
and random.
- For off, the object serializer will never we used.
- For on, the object serializer will be always used.
- For random, the simulator will flip a coin for each
process it starts up.

Status: Count connected coordinators per client
...
A client will always try to connect all coordinators.
This commit let Status track the number of connected coordinators
for each client.
This allows us to do canary in coordinators. For example,
when we switch from non-TLS to TLS, we can switch 1 coordinator
from non-TLS to TLS. This can help check if a client has the ability
to connect through TLS.
We can make the non-TLS to TLS switch for each coordinators
one by one. This avoid the risk of losing connection in the switch.
