Create the initial mClock QoS params at CONF_DEFAULT level using set_val_default(). This allows switching to a custom profile on a running OSD and to make necessary changes to the desired QoS params. Note that Switching to ‘custom’ profile and then subsequently changing the QoS params using “config set osd.n …” will be at a higher level i.e. at CONF_MON. But When switching back to a built-in profile, the new values won’t take effect since CONF_DEFAULT < CONF_MON. For the values to take effect, the config keys created as part of the ‘custom’ profile must be removed from the ConfigMonitor store after switching back to a built-in profile. - Added a couple of standalone tests to exercise the scenario. - Updated the mClock configuration document and the mClock internal documentation with a couple of typos relating to the best effort weights. - Added new sections to the mClock configuration document outlining the steps to switch between the built-in and custom profile and vice-versa.
