Fix keepalived monit job

Previously the keepalived job template for monit was checking if the YML
value `keepalived.enabled` was set to the string value `true`. Instead,
we want to check if it's  boolean value of `true`. This commit fixes
that.

+# Improvements
+
+In this release we've fixed a bug where keepalived was disabled, no matter the
+setting. The intended logic of "keepalived is enabled by default, disabled via
+`keepalived.enabled: false`" holds.
