Currently the sysprofile command is defined in db/commands/test_commands.cpp.
It is (and I think it should remain) the sole user of the util/sysprofile.h and util/sysprofile.cpp code.

I propose that we:

• remove util/sysprofile.h
• move the "sysprofile" command class out into its own source file: db/commands/sysprofile.cpp.
• inline the contents of util/sysprofile.cpp into an unnamed namespace at the top of db/commands/sysprofile.cpp .
• QE would own the new db/commands/sysprofile.cpp file.
