[MNG-7886] Do not warn (or improve warning message) if a profile exists only in the reactor pom, but not in the selected module.

**[Reto Hoehener](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=rho4)** opened **[MNG-7886](https://issues.apache.org/jira/browse/MNG-7886?redirect=false)** and commented

No warning:

```java
mvn -f aggregator/pom.xml -P test-profile validate
```

Warning: 

```java
mvn -f aggregator/pom.xml -P test-profile -pl :module-1 validate
[INFO] Scanning for projects...
[WARNING] The requested profile "test-profile" could not be activated because it does not exist.
```

The build is successful, and the aggregator profile is activated correctly.

**Improvement suggestion:**

Do not warn at all, or:

```java
[WARNING] The requested profile "test-profile" could only be activated in the reactor pom, but does not exist in the selected module "module-1" (this can be intended).
```
