tools/tools-common.h: introduce CGROUP_LOG_CONT level for logging

There are cases, where we might want to print a very long/multiline log
message to the user. We could call the cgroup_log(), multiple times
to fit the log message, but the downside is that every time the
cgroup_log() called, the log level is prefixed to the message, hence
introducing loglevel char string in the mid of the log message.

Introduce a new logging level, CGROUP_LOG_CONT and cgroup_cont() macro,
that will continue printing the log message, when loglevel is set to
other than default log level. The above code can be rewritten as:
