allow inline stacktrace generation

[MarneusCalgarXP]

allow inline stacktrace generation, adding an inline option to net.logstash.logback.stacktrace.ShortenedThrowableConverter

ie:

    <conversionRule conversionWord="stack"
                       converterClass="net.logstash.logback.stacktrace.ShortenedThrowableConverter" />

    <property name="STACKTRACE_PATTERN" value="%stack{full,40,500,rootFirst,inline}"/>
    

    <property name="CONSOLE_LOG_PATTERN" value="%d%d{Z} %-5level [%15.15t] %-40.40logger{39} [%20.20marker] - %replace(%msg){'\n', '\\\\n'} || mdc=[%mdc] ${STACKTRACE_PATTERN} %n"/>
    
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
		<encoder>
			<pattern>${CONSOLE_LOG_PATTERN}</pattern>
		</encoder>
	</appender>

result in a single line :
2022-05-10 11:06:46,859+0200 ERROR [ main] com.example.demo.DemoApplication [ ] - failure || mdc=[] java.lang.IllegalAccessException: a\n at com.example.demo.DemoApplication.lambda$run$0(DemoApplication.java:40)\n at o.springframework.boot.SpringApplication.callRunner(SpringApplication.java:777)\n ... 3 common frames omitted\nWrapped by: java.lang.IllegalStateException: Failed to execute CommandLineRunner\n at o.springframework.boot.SpringApplication.callRunner(SpringApplication.java:780)\n at o.springframework.boot.SpringApplication.callRunners(SpringApplication.java:761)\n at o.springfr...\n

In the meantime I have approved your contribution. A build will now be triggered every time you submit a change. You may have to rebase your work to pickup the latest changes I'm afraid, or the build will keep failing because of issues not related to your work.
