CB-18936 Reformulate roll forward error message, the text of "not cer…

…tified" is misleading

Whenever an upgrade fails, roll forward is automatically invoked. It has a set of error messages stating: "The current Cloudera Manager {0}, Runtime {1} combination is not certified by Cloudera therefore their usage is unadvised and might lead to unexpected errors" The error message is misleading, customers may think they have selected something incompatible, but that is not true. The present commit extends the error message with an explanation, that it is due to an upgrade failure that versions might be incompatible.

Also, in the possible suggestions part the build number of the target CM version was not stated, that is also fixed.

See detailed description in the commit message.

Sample messages produced are:

Because of an upgrade failure, some components are already upgraded, whereas others are not. As a result the current Cloudera Manager 7.4.3-32183016, Runtime CDH 7.2.10-1.cdh7.2.10.p1.15592525 combination is not a certified combination by Cloudera, their usage is unadvised and might lead to unexpected errors. Please continue upgrading them to a certified combination, like Cloudera Manager 7.4.3-32183016, CDH 7.2.11-1.cdh7.2.11.p10.31570330.
