cmake: rearrange configure_file()

AddCephTest and googletest's CMake scripts also call
find_package(Python3...), but they do not specify the required minor
version of Python3. by default, find_package(Python3...) picks the highest
available python3. so, if we have multiple python3 versions installed in the
system, and the highest python3 version is not the one specified by the
-DWITH_PYTHON3=3.x.y in the cmake command line, we might end up using a
different python3 for the ceph CLI. and even worse, the required python3
package might not available for the picked python3 interpreter found by
googletest. as, in general, only a single python3 has the full access to
prepackaged python3-* shipped by a GNU/Linux distro.

in this change, the configure_file() calls are rearranged to the top of
src/CMakeLists.txt, so they have less chance to use the "polluted" cmake
variable for their subvars.

this change address the test failure where we have, for instance, python3.8
installed on RHEL8/CentOS8, where python3.6 is the python3 which has
the access to the python3-* packages.

mgr/cephadm: allow mgr colo if mgr_standby_modules=false

If the standby mgr daemons' modules aren't listening on any ports, then we
can schedule multiple on the same host.

Note that this may make 'orch ps' output misleading, as ports will be
reported for each mgr instance, but only one of them will actually be
listening at any one time (if they are behaving, at least!).  Treat a
mgr port check error as non-fatal.

mgr/MgrStandby: add mgr_standby_modules option

Add config option to control whether the standby modules are started.
Default to true (no change in behavior), but if set to false the standby
mgr modules don't do the redirect business.

This option controls the rate of trimming of onodes and the earlier default of
64 has been seen to be too low for large clusters, leading to buildup of

Increase the default value to 1000, since there are no known downsides to it.
