Deprecate Standard Plugin

[cdsap]

Talaiot standard plugin is growing.
After the latest development of the InfluxDb2 Plugin, we didn't include the new plugin on the standard plugin. The initial purpose of the plugin was to give compatibility with the older monolith model. For the next major release, I'm proposing to deprecate it and follow the plugin model for the different infra supported.
To achieve the deprecation we would need:

• Offer a base publisher functionality(json/timelinepublisher/output) on the Talaiot core. This won't affect the Base plugin, still I think is interesting to provide a minimum plugin to facilitate extensions on the client side.
• Remove the standard plugin.
