Dump active configuration at every start and configuration reload

[gw0]

SUMMARY

When debugging issues it is helpful to see the exact config file that is being used by oasis-node. On one hand node operators typically forget to provide it, on the other hand with envsubst support and the upcoming config hot-reloading it will be even less obvious what configuration is being used.

I suggest that at every start (and configuration reload) the active oasis-node configuration is dumped into logs at debug level (maybe as a base64-encoded one-line log entry).
