Let straightforward `vidkeystorepassword` setting in values.yaml

The value of vidkeystorepassword is plugged as environment variable
VID_KEYSTORE_PASSWORD. (see commit 7a3e2594; change-id:
Ibf52542344ecf79fb947858329f37018731d2270)

Now CATALINA_OPTS will be evaluated when container is started, with
the actual value of VID_KEYSTORE_PASSWORD env variable.

This fixes the issue where CATALINA_OPTS is evaluated at Docker
build time, with a static VID_KEYSTORE_PASSWORD value.
