Add params_to_tune for linear models

[Mr-Geekman]

🚀 Feature Request

Define params_to_tune for liner models.

Proposal

Sources for the grid:

• pycaret
  • linear
  • elastic
• kats

Suggested grid for linear (not elastic):

{
    "fit_intercept": CategoricalDistribution([False, True]),
}

Suggested grid for elastic:

{
    "fit_intercept": CategoricalDistribution([False, True]),
    "l1_ratio": UniformDistribution(0, 1),
    "alpha": LogUniformDistribution(low=1e-5, 1e3),
}

Test cases

Look at #1184.
