Rename `rippled.cfg` to `xrpld.cfg`

[bthomee]

High Level Overview of Change

This change renames all occurrences of rippled.cfg to xrpld.cfg. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts. For the time being it maintains support for rippled.cfg as config file, if xrpld.cfg does not exist.

Context of Change

Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).

This change essentially ensures that the config file will now be named xrpld.cfg. At the same time, everyone can keep using the config file named rippled.cfg. The plan is to remove support for rippled.cfg` in about 6 months to give everyone plenty of time to update the config file name.

Lots of rippled references in the xrpld.cfg. Should path=/var/lib/rippled/db/nudb be path=/var/lib/xrpld/db/nudb?

Thanks for pointing this out. I adjusted the script to also rename inside the config file. There are many other files with references too, but those can be done as a separate clean up PR afterwards.

Regarding the paths, I renamed those too in the example config. I did not touch the config that someone might have stored in the repo root for testing, since they might depend on the current paths.
