0c6a7db3ba ctdb-recoverd: Flatten update_flags_on_all_nodes()
The logic currently in ctdb_ctrl_modflags() will be optimised so that
it no longer matches the pattern for a control function.  So, remove
this function and squash its functionality into the only caller.

Although there are some superficial changes, the behaviour is
unchanged.

Flattening the 2 functions produces some seriously weird logic for
setting the new flags, to the point where using ctdb_ctrl_modflags()
for this purpose now looks very strange.  The weirdness will be
cleaned up in a subsequent commit.

where $test_node is not set, a fixed node that is already used

37c26a9590 ctdb-tests: Separate custom cluster startup from test initialisation
Separate cluster startup from test initialisation for tests that start
the cluster with customised configuration.  In these cases the result
of the cluster startup is actually the point of the test.
Additionally, pubips.013.failover_noop.sh claims to have completed
test initialisation twice, which just seems wrong.

The result is:

* ctdb_test_init() takes one option (-n) to indicate when it should
  not configure/start the cluster

* New function ctdb_nodes_start_custom() accepts options for special
  cluster configuration, only operates on local daemons and triggers a
  test failure rather than a test error on failure.

be3065ea95 ctdb-tests: Make integration.bash pass shellcheck
Apart from the non-constant sourcing of include files.

Mostly avoidance of quoting warnings.

One subtle change is to simply pass "120" to wait_until_ready() to
stop warnings that it expects arguments but none are passed (both
SC2119 and SC2120).  There seems no way to indicate to structure
function argument handling so that shellcheck realises arguments are
optional.  In later shellcheck versions, disabling SC2120 for a
function also silences complaints about its callers... but not all of
our testing uses "later" shellcheck versions.
