Kubernetes-commit: a9593d634c6a053848413e600dadbf974627515f
* Remove linter warnings.
* Cancel contexts to avoid leaks.
* Rename a few XXXThreadUnsafe to XXXLocked to
maintain consistency.
* A few are still called XXXThreadUnsafe mainly
because those are safe to be called from the
perspective that only one gorotuine will access
them - not really called under a lock.

watchCacheInterval serves as an abstraction over a source
of watchCacheEvents. It maintains a window of events over
an underlying source and these events can be served using
the exposed Next() API. The main intent for doing things
this way is to introduce an upper bound of memory usage
for starting a watch and reduce the maximum possible time
interval for which the lock would be held while events are
copied over.
The source of events for the interval is typically either
the watchCache circular buffer, if events being retrieved
need to be for resource versions > 0 or the underlying
implementation of Store, if resource version = 0.
Furthermore, an interval can be either valid or invalid at
any given point of time. The notion of validity makes sense
only in cases where the window of events in the underlying
source can change over time - i.e. for watchCache circular
buffer. When the circular buffer is full and an event needs
to be popped off, watchCache::startIndex is incremented. In
this case, an interval tracking that popped event is valid
only if it has already been copied to its internal buffer.
However, for efficiency we perform that lazily and we mark
an interval as invalid iff we need to copy events from the
watchCache and we end up needing events that have already
been popped off. This translates to the following condition:
watchCacheInterval::startIndex >= watchCache::startIndex.
When this condition becomes false, the interval is no longer
valid and should not be used to retrieve and serve elements
from the underlying source.
