When the base-path for the actuator is set to `/` on spring boot 2 the
endpoints can't be queried via the actuator index and need to be probed.
Therefore we need to probe not only for the old names but also for the
names in boot 2.0.

Everythind that looks like an http(s) url will be rendered as hyperlink
and ansi-color escapes are now supported.

In order to have ansi-colors in the file output you need to set a custom
pattern. e.g.:
logging.pattern.file="%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(%5p) %clr(${PID}){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n%wEx"

Before this, the route was always lower-cased, but this makes the route registered with Spring Boot Admin not accessible. This changes to use the route as it is, and updates a test to include an uppercase letter in the route.

Add a page with extra button to trigger a heap dump.

server.servlet.contextPath set

As Spring Boot 1.4.x and older doesn't use the vendor content-type for
the actuator endpoints, we also need to consider application/json
responses for the legacy conversion

fixes #749

The to/from statuses were previously inverted.
Test message contents in tests for MicrosoftTeamsNotifier.doNotify().

The caches.size metric is not available for every cache implementation.
If the metric is not available the ui should still show hits and misses.
This commit ignores errors for the cache size and will do no further
requests for this metric after an error occurred.

fixes #756

Setting a loglevel for logger names with spaces currently fails because
the servlet.InstanceProxyController messes with the encoding. With this
commit the path is correctly encoded before being forwarded.
