Change retrials -> retries

[dbeltrankyl]

Hello @BSC-ES/autosubmit

From @tiggi, mattermost:

Whoever touches autosubmit code: retrial and retry are completely different things. AS code is full of references to retrial in both log messages and as variable names. It does not mean what you think it means.

For a retrial you go back to court and redo the original trial.

https://en.wiktionary.org/w/index.php?title=retrial&rdfrom=Retrial

So, we have to change retrials -> retries everywhere.

This means that some exportable variables need to be renamed as well. To avoid breaking anything, I propose doing it for 4.2+.

+1 for 4.2. Maybe we could support both for a while, but raise a deprecation warning telling users to update to the new value.
