Fuse 7.3: change OSGi import ranges to match Fuse 7.3/Undertow 2

Fuse 7.3 made an alignment with EAP 7.2 with respect to used servlet API and container.

Fuse 7.3 supports:

• servlet API 4.0
• Undertow 2

Thus all bundles that import io.undertow.* or javax.servlet.* packages should change the import range:

• undertow: [1.4,3) (looks like it's already there)
• servlet API: [3.1,5) (now it's [3.1,4.0))
