When @ConditionalOnBean or @ConditionalOnMissingBean are used on a
@Bean method, they will, in the absence of any other configuration,
attempt to deduce the bean's type by examining the method's return
type. This deduction can fail. See gh-4841, gh-4934, and gh-5624
for some examples of possible failure causes. Previously, this
failure was only logged as a debug message leaving the user with a
misleading message suggesting that the @ConditionalOnBean or
@ConditionalOnMissingBean annotation was not configured correctly.

This commit improves the diagnostics by mention the possibility of
type deduction in the exception message and including the exception
that caused deduction to fail as the cause.

Closes gh-4934

TestPropertySourcesInitializer needs to be ordered with a high
precedence, specifically higher than
ContextIdApplicationContextInitializer, to ensure that any properties
used in setting the context’s id are available in the environment.

Closes gh-4828

The Mustache support should still be usable outside a web application
because the properties only use web stuff in that context and don't
have any field or method signatures that depend on web.

Fixes gh-5626

This commit updates the precedence of properties configured using
@SpringBootTest to align with @TestPropertySource. Properties configured
using properties on @SpringBootTest are now added to the same property
source as those configured using properties on @TestPropertySource so
the precedence described in the javadoc of @TestPropertySource now
applies in full. Additionally, if both @TestPropertySource properties
and @SpringBootTest properties configure the same property, the value
from @TestPropertySource will win.

Closes gh-4828

  Update JarURLConnection to support jar:file://… URLs

Previously, JarURLConnection would fail when created with a URL that
began with jar:file:// as the double-slash is not included in jarFile.getUrl().getFile().

This commit updates JarURLConnection to normalise the value return from
url.getFile() to remove a double-slash when present.

  Improve repeatability of launch script tests

Previously, tags were used for CentOS and Ubuntu images that may
change over time. This commit updates the Dockerfiles to use fixed
base images. For Ubuntu, a fixed tag is available. For CentOS we
have to resort to using the digest.

  Allow per-http-method MetricsFilter submissions

Add `endpoints.metrics.filter.gauge-submissions` and
`endpoints.metrics.filter.counter-submissions` properties which can be
used to fine-tune how MetricsFilter submits metrics.

Use `per-http-method` to group by the the HTTP method, `merged` to
combine or both (`merged,per-http-method`) to submit both in forms.
