Make some of the j2 templates source configurable

[talek]

For some custom/advanced setups it would be nice if we could customize some of the default provided templates. It is the case of motd.j2 template from the common role, sudoers.j2 from the orahost role (if for example I don't want NOPASSWD for sudo or I'd like access to a few commands only) and dotprofile-home.j2 from oraswdb-install role. With the proposed changes I can create for example my own dotprofile-home.j2, place it in my templates/ folder in the root of my playbook directory and set oracle_profile_template to "{{ playbook_dir }}/templates/dotprofile-home.j2". I can do all these manually through some post_tasks, of course, but it would unnecessarily complicate the playbook. Not to mention that generating dotprofile file can't be currently disabled. This patch adds also a new configure_oracle_profile variable to control whether the profile file should be generated.

Looks fine except the default for configure_oracle_profile: true.
The old .profile has some issues and was replaced by ocenv. That's why the default has changed to false.

Hmm... on my default 19c setup I always end up with a .profile_19c file, so I thought this is always generated no matter what. That is why I set the configure_oracle_profile: true, just to ensure backward compatibility. Otherwise, I'm fine with setting it to false as default.

Sorry, you are right. It is installed by default.

I'll place it on the deprecation list, because the old environment has some errors, which I won't fix anymore due to the replacement by `ocenv.

=> PR is fine for me.
