Fix error message in multi-host configuratiion

[r4nd0m]

When the tomcat is configured for multiple hosts, the following message is being displayed on startup:
"static path [/opt/lucee/web/] for servlet init param [lucee-web-directory] is not allowed. Path must use a web context specific placeholder"
Tha cause is a hardcoded lucee-web-directory.

Thats ok, for me

I think this would affect all existing web context paths (e.g. /opt/lucee/web/logs would become /opt/lucee/web/{web-context-label}/logs) so some users volume mappings could fail. We might need to solve this a slightly different way so that use cases for existing paths aren't impacted.

Good point @justincarter, how about adding:
<labels><label id="some_id_hash" name="./"/></labels>
to the /opt/lucee/server/lucee-server/context/lucee-server.xml
so we have a default label whose path will be resolved to the /opt/lucee/web/ in case we have only one context?

I tested it in my single-context container by renaming the label (without changing the path to the config file, it has been changed automatically) and it looks like that worked
