typo: Possible typo in documentation: ‘loggin’ should be ‘logging’”

[wzq1022]

spring-cloud-commons/docs/modules/ROOT/pages/spring-cloud-commons/application-context-services.adoc

Line 153 in a0ec693

For example, using `custom.loggin.logpath` is not recognized by Spring Cloud when initializing the logging system.

I'm not sure, if not a typo, please close this issue, thanks.
