James Tucker 68b12a74ed metrics,syncs: add ShardedInt support to metrics.LabelMap
metrics.LabelMap grows slightly more heavy, needing a lock to ensure
proper ordering for newly initialized ShardedInt values. An Add method
enables callers to use .Add for both expvar.Int and syncs.ShardedInt
values, but retains the original behavior of defaulting to initializing
expvar.Int values.

Will Norris 71029cea2d all: update copyright and license headers
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

David Anderson f192c05413 metrics: add a LabelMap type for variables with 1 label dimension.
This lets us publish sets of vars that are breakdowns along one
dimension in a format that Prometheus and Grafana natively know
how to do useful things with.
