[KARAF-3262] feature configfile: substitution
Add variable substitution to the configfile finalname of a feature.
Old situation:
* All ${...} are removed from the config file name and not used.
* The given path is prefixed with / relative to ${karaf.base} on
installation
New behaviour:
* If the final name starts not with "${", the path is prefixed with /
relative to karaf.base.
* All ${...} are substituted.
* If the substituted string starts with an variable (the first one
* has
been unknown), it is prefixed with / relative to karaf.base.
* All unknown variables are removed from the resulting final name.

Here some testing:
```java
public static void main(String[] args) {
System.setProperty("karaf.base", "/tmp/karaf.base");
System.setProperty("foo1", "/foo1");
final String[] finalNames = {
"etc/test.cfg",
"/etc/test.cfg",
"${karaf.base}/etc/test.cfg",
"etc/${foo1}/test.cfg",
"${foo1}/test.cfg",
"etc${foo2}/${foo2}test.cfg",
"${foo2}/etc/test.cfg${foo2}",
"${karaf.base}${foo2}/etc/test.cfg",
"etc${}/${foo1}/test.cfg",
"${foo1}/test.cfg",
};
for (final String finalName : finalNames) {
System.out.println(finalName + " => " + substFinalName(finalName));
}
}
```
Result (the exception is catched, kept logging):
```java
etc/test.cfg => /tmp/karaf.base/etc/test.cfg
/etc/test.cfg => /tmp/karaf.base//etc/test.cfg
${karaf.base}/etc/test.cfg => /tmp/karaf.base/etc/test.cfg
etc/${foo1}/test.cfg => /tmp/karaf.base/etc//foo1/test.cfg
${foo1}/test.cfg => /foo1/test.cfg
etc${foo2}/${foo2}test.cfg => /tmp/karaf.base/etc/test.cfg
${foo2}/etc/test.cfg${foo2} => /tmp/karaf.base//etc/test.cfg
${karaf.base}${foo2}/etc/test.cfg => /tmp/karaf.base/etc/test.cfg
etc${}/${foo1}/test.cfg => /tmp/karaf.base/etc//test.cfg

> Reporter: Jean-Baptiste Onofré
> Assignee: Jean-Baptiste Onofré
>
> The <configfile/> element in a feature accepts a finalname attribute to
> define where the configfile has to be copied.
> However, finalname is relative to ${karaf.base}, whereas it should be able to
> use ${karaf.etc} (and so relative to ${karaf.etc}).
> In order to be backward compatible, if finalname starts with /etc/ it will be
> relative to ${karaf.base}, else it will be related to ${karaf.etc}.
