MDEV-28986: rpl tests sometimes failing on freebsd builders

The rpl_row_img_sequence test can fail on resource
constrained buildbot machines due to its high
space consumption. To reduce this footprint, the
test is split into three parts, one for each value
of the binlog_row_img variable.

+# Purpose:
+#   The rpl_row_img_sequence group of tests verify that sequence MDL updates,
+# i.e. NEXTVAL and SETVAL, respect the binlog_row_image variable value when
+# written into the binary log. In particular, it ensures that only changed
+# columns are written with MINIMAL image mode, and all columns are written
+# otherwise. This test focuses on validating the behavior of
+# binlog_row_img=FULL.
+#
+# Methodology
+#   After issuing a sequence update, ensure that both 1) it was replicated
+# correctly, and 2) it was binlogged respective to the binlog_row_image value.
+# The sequence table does not use caching to ensure each update is immediately
+# binlogged. Each command is binlogged into its own unique log file, and the
+# entirety of the file is analyzed for correctness of its sequence event.
+# Specifically, mysqlbinlog is used in verbose mode so it outputs the columns
+# which belong to the event, and the columns are analyzed to ensure the correct
+# ones were logged. rpl_row_img_general_loop.inc is used to test with multiple
