Flugin: fix InstallPlugin() API by manually creating RPC code
previous implementation of InstallPlugin()-#12232 's RPC funcs wasn't working because `io.Reader` isn't supported by the RPC code generation tool.
RPC does not support streaming data and RPC code generation tool does not handle this exception.
thus, RPC funcs are now implemented manually to stream `io.Reader` through a separate multiplexed connection.
* Adding interplugin communication.
* Naming changes and moving ResponseTransfer to own file.
* Fix.
* Tests and moving to buffering bytes.
* Switching API to passing plugin ID through path rather than a header.
* Review feedback.
- Add stringutils with method that "stringify" object slices
- "stringify" means convert each object to its string representation
- Move plugin.Log* implementations to client_rpc, use stringify method before calling server method
- Exclude Log* methods from generated RPC methods
- No signature change for plugin.Log* API
- Add test in plugin_api_test to use plugin.Log* methods with RPC
* Prevent clobbering of new fields by old plugins.
* Apply suggestions from code review
Spelling and copy paste error.

We never actually initialized `log` on apiRPCClient, and it can't log
without making an RPC call anyway, so just switch to logging errors from
the plugin to STDERR instead.
* clean up plugins GoDoc:
- eliminate plugin.NewBlankContext() as unnecessary
- export ValidIdRegex as a string vs. the less readable var
- add/update various documentation strings
- hide everything by default, except where used by client plugins or the mattermost-server. The exception to this rule are the `*(Args|Returns)` structs which must be public for go-plugin, but are now prefixed with `Z_` with a warning not to use.
- include a top-level example to get plugin authors started
This is not a breaking change for existing plugins compiled against
plugins-v2.
* remove commented out ServeHTTPResponseWriter
* update examples to match developer docs
* add missing plugin/doc.go license header
