  Fix springProfile with multi profiles separated by comma and whitespace

Previously springProfile supported multi profiles separated by comma but
it doesn´t work if there are whitespaces. Now, springProfile will read
values cleaning whitespaces.

  Add `spring.mvc.static-path-pattern` property

Add a `spring.mvc.static-path-pattern` property which can be used to
configure the path pattern used to serve static resources.

Along with the recent change in Spring to use content-disposition
"inline" (which prevents the download), it also makes sense to limit
the extensions allowed by the actuator endpoints. Really there *is*
no extension for these endpoints, but since all of them explicitly
produce JSON we can add .json for browsers as a convenience in case
the app would otherwise choose to send XML.

Fixes gh-4402

Fixes gh-4366

Fixes gh-4384

Update EndpointHandlerMapping so that setUseSuffixPatternMatch is set
to false. This prevents URLs of the form /beans.json from returning
results and provides another line of defense against RDF attacks.

Update SpringApplication so that startup exceptions are only logged
once. A custom UncaughtExceptionHandler is now used when running in
the main thread to suppress errors that have already been logged.

* pr/4333:
  Improve resource handling in LogFileMvcEndpoint

Update `LogFileMvcEndpoint` to use a `ResourceHttpRequestHandler` when
serving the log file resource. This gives support for requesting parts
of the logfile via the HTTP Range header. Requests with the
`If-Modified-Since` header are now also handled correctly.

Closes gh-4333

* pr/4409:
  Auto-configure CassandraHealthIndicator

Add auto-configuration for the CassandraHealthIndicator. Also update
the implementation to use CassandraOperations rather than
CassandraAdminOperations.

Closes gh-4409

  Make OPTIONS/TRACE request handling configurable

Add properties to WebMvcProperties allowing control of if TRACE/OPTIONS
requests should go through the regular dispatching chain.

Closes gh-4300

* pr/4237:
  Switch MongoCredential method

Update MongoProperties to use `MongoCredential.createCredential` rather
than `MongoCredential.createMongoCRCredential`. This allows connections
to Mongo 3.0 servers to authenticate using the SCRAM-SHA-1 mechanism.
