modules: add slf4j-nop where it is missing

Default startup of elasticsearch results in warnings:

> [WARN ][stderr ] [es] SLF4J: No SLF4J providers were found.
> [WARN ][stderr ] [es] SLF4J: Defaulting to no-operation (NOP) logger implementation
> [WARN ][stderr ] [es] SLF4J: See https://www.slf4j.org/codes.html#noProviders for further details.

It seems like most modules and plugins install nop logger, but some
don't. If one installs them everywhere, these warnings seem to go
away.
