[spring-boot] Use spring boot starter instead of spring libraries for building and starting context.

[HomeOfTheWizard]

Currently we use the following seperate dependencies for managing a spring context.

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>5.3.16</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>5.3.16</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>5.3.16</version>
        </dependency>

This keeps the effective dependency tree small but Spring starters are a better idea. This will give multiple new features without managing the interoperability of the different lib versions.
