I talked about this issue with @juzhiyuan offline and we have reached the
following consensus:
1. To improve the user experience, we would add plugin configuration
templates, which are a range of configurations based on the different use
scenario, in the templates, we should add instructions for each configuration
item at the same time.
**where would these configuration template stored?**
Stored in files would be better. Create a template file for each plugin
under something called `doc/plugin_templates` dir in dashboard
**what is the template file type?**
The type of the template file can be `markdown` or `yaml`. `yaml` would
be easier to parse
**what would the template look like?**
This needs further discussion. may be we can use follows:
take limit-conn for an example
```yaml
scenario1: # limit concurrency per client's IP
conn: 1 # the maximum number of concurrent requests
allowed
burst: 0 # the number of excessive concurrent requests
(or connections) allowed to be delayed
default_conn_delay: 0.1 # the default processing latency of a typical
connection
rejected_code: 503 # returned when the request exceeds conn + burst
will be rejected, default is 503
key: "remote_addr" # limit the concurrency level
scenario2: # limit concurrency per server's IP
conn: 1 # the maximum number of concurrent requests
allowed
burst: 0 # the number of excessive concurrent requests
(or connections) allowed to be delayed
default_conn_delay: 0.1 # the default processing latency of a typical
connection
rejected_code: 503 # returned when the request exceeds conn + burst
will be rejected, default is 503
key: "server_addr" # limit the concurrency level
...
```
2. To support instructions in the configuration templates, we should use
`yaml` instead of `json` in dashboard plugin codemirror.
3. in the plugin config page, we would add a select box to select
configuration template, and show the template configuration in the codemirror:

Welcome any suggestions to improve the program
