* Debug version of fdbserver -r changeclusterkey tool
* Remove debug symbols; move function to Coordinaton.actor.cpp
* Format and add traces
* fix comments
* Adds ddsketch_calc.py which implements a class for DDSketch related calculations
* Adds ddsketch_conversion.py for quickly computing a bucket index to a value or vice-versa
* Adds ddsketch_compare.py to compute how similar two ddsketch distributions are
* Adds export_graph.py to graph the ddsketch distribution outputted from mako
The arguments for ddsketch_conversion.py are:
-b, --bucket: the bucket index that we need to calculate the value from (optional)
-v, --value: the value that we need to calculate the bucket index from (optional)
-e, --error_guarantee: the error guarantee for ddsketch (optional, default is 0.005)
The arguments for ddsketch_compare.py are:
--file1: Path to first ddsketch json
--file2: Path to second ddsketch json
--txn1: The transaction type for the first file
--txn2: The transaction type for the second file
--op: The operation name (ex: GRV, GET ...)
The arguments for export_graph.py:
--file: path to ddsketch distribution
--txn, -t: Transaction type from file
--title: title for graph (optional, otherwise "Title" is used)
--savefig: Path to save the image plot (optional)
--op: Which operation to plot
* Use enum variables to invoke Priority checking

* Set up RelocateShard in terms of data movement reason instead of priority
* Remove isMountainChopperPriority
* Remove isDiskRebalancePriority
* Fix formatting

fdbserver/storageserver.actor.cpp:654:24: error: cannot pass object of non-trivial type 'const std::string' (aka 'const basic_string<char, char_traits<char>, allocator<char>>') through variadic function; call will abort at runtime [-Wnon-pod-varargs]
Just use fmt instead
Clients now poll the proxy for the latest global config for a specific
version. The proxy now periodically requests the latest global
configuration data and stores it in memory, enabling it to respond
immediately to clients with the appropriate version.
Clients should avoid reading system keys unless authorized. Under global
config, each client reads from the system keyspace to check for new
global config keys. This commit moves these reads to a server role (the
GRV proxies) and sends the results back to GlobalConfig for an in-memory
update.
* Storage server shard management with physical shards.
* Cleanup.
* Resolved comments.
* Added `UnlimintedCommitBytes`.

* Add extra validation to special key space reads in simulation
* Fix bugs turned up by validating subrange reads
* Change to validateSpecialSubrangeRead
It is in general not safe to expect that a read from the special key
space returns the same results if performed again, since the
transaction may be being modified concurrently.
* Add comment
* Add comment
* Don't build fdb c shim with ubsan
This avoids duplicate symbols when linking. It doesn't really make sense
to assemble files with -fsanitize=undefined anyway, since it won't
insert instrumentation.
* Consolidate boost_asan with boost_target
