gfapi: add API to trigger events for debugging and troubleshooting
Introduce glfs_sysrq() as a generic API for triggering debug and
troubleshoot events. This interface will be used by the feature to get
statedumps for applications using libgfapi.
The current events that can be requested through this API are:
- 'h'elp: log a mesage with all supported events
- 's'tatedump: trigger a statedump for the passed glfs_t
In future, this API can be used by a CLI to trigger statedumps from
storage servers. At the moment it is limited to take statedumps, but it
is extensible to set the log-level, clear caches, force reconnects and
much more.
