Add an `DispatcherServletPath` interface which provides a much more
consistent way to discover the path of the main dispatcher servet.
Prior to this commit, auto-configurations would often make use of the
`ServerProperties` class to discover the dispatcher servlet path. This
mechanism isn't very explicit and also makes it hard for us to relocate
that property in Spring Boot 2.1.
This commit also reverts most of fddc9e9c7e since it is now clear that
the supporting multiple dispatcher servlet paths will be much more
involved that we originally anticipated.
Closes gh-13834
This commit also contains changes to `ServletContextInitializerBeans`.
`ServletContextInitializerBeans` can now be configured to only look
for specific ServletContextInitializer subclasses, defaulting to
ServletContextIntializer.class. `SpringBootMockMvcBuilderCustomizer`
only cares about filters so it was unnecessary to look for all
`ServletContextInitializer`s. Additionally, adapting `Servlet` beans
caused a cycle once the `DispatcherServlet` bean was added and the
customizer only needs to adapt `Filter` beans.

Auto-configuration of LDAP's `LdapTemplate` is currently a part of
`LdapDataAutoConfiguration` which is conditional of presence of
`LdapRepository` (i.e. Spring Data LDAP). This arrangement isn't ideal
since the `LdapTemplate` is a part of Spring LDAP project, and therefore
should not be tied to Spring Data LDAP.
This commit improves and simplifies LDAP auto-configuration by moving
`LdapTemplate` configuration to `LdapAutoConfiguration`. Consequently,
`LdapDataAutoConfiguration` is not needed anymore and is removed.

This commit updates WebTestClientAutoConfiguration to only create a
WebTestClient when running a WebFlux-based application as mocking the
context only works with that mode at the moment.
