Consider pre-existing xd.home system property
For both ContainerMain & AdminMain, XD home is set in the following ways:

1) From xd-* scripts, specify "--xdHomeDir" command line option.
   This will override any existing system property "xd.home".
2) If "--xdHomeDir" is not specified, then the "xd.home" system property will
   have the preference
3) If both "--xdHomeDir" and "xd.home" system property are not provided,
   then the relative path ".." is set to be XD home
XD-199 Support DELETE Operation with Tap

In order to delete the inbound adapter/bridge for
a tap, the registry needs to track the name of the
tap the endpoint is for.

Enhance metadata in LocalChannelRegistry to include
the tap stream name.

In RedisChannelRegistry, include tap stream name in
the adapters componentName.
