Regular expressions in the namespaces package are redundant with the
pre-existing validator in the "identifiers" package; replace this custom
usage with the validator in "identifiers"

By defining a concrete, non-protobuf type for the events interface, we
can completely decouple it from the grpc packages that are expensive at
runtime. This does requires some allocation cost for converting between
types, but the saving for the size of the shim are worth it.

To avoid importing all of grpc when consuming events, the types of
events have been split in to a separate package. This should allow a
reduction in memory usage in cases where a package is consuming events
but not using the gprc service directly.
