Add gradle runJar

Lazy initialization of management server properties
Important: restrict PPC scanning to current context
Add SpringApplicationBuilder

Builder for SpringApplication and ApplicationContext instances with
convenient fluent API and context hierarchy support. Simple example
of a context hierarchy:

   new SpringApplicationBuilder(ParentConfig.class)
               .child(ChildConfig.class).run(args);

Another common use case is setting default arguments, e.g.
active Spring profiles, to set up the environment for an application:

     new SpringApplicationBuilder(Application.class).profiles("server")
 		.defaultArgs("--transport=local").run(args);

If your needs are simpler, consider using the static convenience
methods in SpringApplication instead.

[#49703716] [bs-116] Parent context for some beans maybe?
Refine SpringApplicationBuilder and add a test for profiles
Add SpringApplicationContextLoader
Added Spring Boot Guides from spring.io
Spelling error: "everypone"
Add schema.sql,data.sql to default SQL initializers

...for compatibility with Spring JDBC. Users can still
optionally specify spring.database.schema, but the default
location is schema-${spring.database.platform}.sql, schema.sql,
data.sql.

Investigating
Fix bug with ordering of property sources

Profile-specific property sources were being added last,
*after* the global values, which means they did not
override in the way that users would expect.

Fixed by storing the global property sources in an
intermediate list and applying them after the profile
specific ones.
Add documentation on how to use gvm to support CLI dev work
Added AMQP starter and sample
Tweak AMQP sample slightly
Add amqp starter to build
Added test for AOP auto configuration and dependency to AspectJ
Make default proxyTargetClass=false

If the default is true JPA repositories all have to have
default constructors etc.
Use create_drop JPA as default if in-memory
