- it does multiple iterations, like the upmap optimizer.
- it decreases the step size if it isn't improving, in the hope
that it is overshooting the minimum
- debug output is cleaned up a bit (the info level should be
genuinely useful)

Otherwise, when someone wants to see what's possible
to do with `mgr module enable` they have to trawl
through the whole mgr map dump.

Some extra coverage of the dashboard, including its standby
redirect mode and the publishing of URIs.
Also invoking the command_spam mode of the selftest module.

These didn't need to keep the GIL to go and do their
pure C++ parts, and by keeping it they could deadlock
while trying to take ActiveMgrModules::lock.

A bunch of the previous commits were done
before this class existed, so updating in
one go instead of trying to edit history
in fine detail.

Was passing a reference to a local stringstream into
Thread::create, not realising that it was taking a char*
reference instead of a copy. Result was garbage (or usually,
all threads having the name of the last one created)

Modules can implement a second, separate class
that has access to very little state about the
system and can't implement commands.
They have just enough information to redirect
or forward incoming requests/traffic to the
active instance of the module on the active mgr.
This enables module authors to create modules
that end users can access via any (running) mgr node
at any time, rather than having to first work out
which mgr node is active.

Separate out the *loading* of modules from
the *running* of modules.
This is a precursor to enabling modules to run
in standby mode.

Expose a python class instead of a module,
so that we have a place to carry our reference
to our MgrPyModule* and to PyModules*, rather than
passing a handle for the former and using
a global pointer for the latter.

This was kind of unnecessary, highlighting a completely normal
and healthy situation in a different colour. The blue was
also really hard to read against a grey background.
