I forgot to mention that in the case of qualifier metadata existing at a higher level in
MDR than instance level, the search takes that into account and merges whatever it can
find at all levels. e.g., if ["a", "b"] exists at JVM level and
["c", "d"] at INSTANCE level, when doing the lookup for an instance
["a", "b", "c", "d"] is returned.

use/expand AbstractInjectionValueMetaData to use qualifiers.
I've done this. This differs from the bean-level qualifiers in that if a qualifier
exists on an injection point, then the bean-level qualifiers are ignored, so the property
level ones completely override the bean level ones e.g.
| class TargetBean
| {
| Bean bean1;
|
| Bean bean2;
| }

If the bean has RelatedClassMetaData specifying that it's wanted qualifiers are
'A', and the property bean2 specifies that the qualifiers are 'B', for
bean1 we will inject a bean that supplies the qualifier 'A', while for bean2 a
bean that supplies the qualifier 'B' will be injected.
I don't know if the qualifiers for the injection points should be read from the MDR or
not? At first glance doing that does not make sense since the component metadata lives
below instance level, but I might be wrong. Especially if my previous assumption that
injection point qualifiers should completely override the bean-level wanted qualifiers is
wrong?
I'll add some xml configuration for everything before I commit
