Support more GPT models in Mage + allow customizing both of them (#1598)

* Enable new OpenAI models for MAGE

* Add option to specify Plan GPT model from CLI

* Fix error in parsing planGptModel

* Remove check for GPT-4 availability

* Refactor initialization of GPT params

* Add GPT 3.5 Turbo 0613

* Fix GPT versions to exact values

Generic OpenAI models, such as 'GPT-4' and 'GPT-3_5_turbo',
point to the 'latest' of the respective OpenAI models.
This means that the exact models used can change unexpectedly.
This would not normally be an issue, but the newer models
tend to exhibit a performance drop.
Therefore, to future-proof our application, we fix the
model versions to prevent any unexpected model changes.

* Rename base->coding, plan->planning

* Remove unused _useGpt3IfGpt4NotAvailable field

* Remove confusing helper function

* Fix typo Planing -> Planning
