Add completion for dependency-check.sh

[jeremylong]

Add script for completion for dependency-check.sh so we can more easily select the correct arguments. After installing completion-for-dependency-check.sh (using source completion-for-dependency-check.sh) we can list the arguments using <tab><tab>. The following example lists all of the --disable* arguments:

$ ./dependency-check.sh --disable<tab><tab>
--disableArchive                      --disableCocoapodsAnalyzer            --disableNodeAuditCache               --disablePip
--disableAssembly                     --disableComposer                     --disableNodeJS                       --disablePipfile
--disableAutoconf                     --disableGolangDep                    --disableNugetconf                    --disablePyDist
--disableBundleAudit                  --disableGolangMod                    --disableNuspec                       --disablePyPkg
--disableCentral                      --disableJar                          --disableOpenSSL                      --disableRetireJS
--disableCentralCache                 --disableMixAudit                     --disableOssIndex                     --disableRubygems
--disableCmake                        --disableNodeAudit                    --disableOssIndexCache                --disableSwiftPackageManagerAnalyzer

Consider adding source <path>/completion-for-dependency-check.sh to your .bashrc if you use ODC a lot.
