This commit makes sure that all usages of String toLowerCase and
toUpperCase specify a Locale (default of Locale.ROOT).
Also, a checkstyle rule is added to prevent usage of the no-arg variant
of String toLowerCase and toUpperCase.
This adjusts the `PulsarTemplate` to log a warning when a user provides
a `ProducerBuilderCustomizer` that is implemented as a Java Lambda.
This is important as the customizer is used as part of the producer
cache key and if not implemented properly will effectively disable
producer caching and write performance will degrade.
