Renegotiation setting missing in tls.Config

[simitt]

When configuring ssl/tls users can configure a Renegotiation option. This option is set in the TLSConfig but not passed to tls.Config.
Thus, BuildModuleConfig ignores the configured renegotiation option and uses the default.

While at it, as @andrewkroh pointed out, there is also a typo in the yml config for renegotiation.
