This commit also switches to RSocket SNAPSHOTs and updates the
repository configuration to rely on "libs-snapshot", since the RSocket
SNAPSHOTs are mirrored there.

  Use milliseconds when configuring awaitTerminationPeriod

Closes gh-22604

See gh-22604

Prior to this change, TaskExecutorBuilder used seconds as its precision
to map the awaitTerminationPeriod value. This caused a loss of
millisecond information in the period.

This commit fixes the loss by converting the period to millisecond and
using setAwaitTerminationMillis to configure the executor.
