Organize EDA methods into folders

Motivation

Make it easier to find the nesessary method

Proposal

a) Create the following structure of files in etna/analysis:

1. anomalies

• outliers_detectors -- folder with search method
• plotters.py: plot_anomalies, plot_anomalies_interactive, plot_holidays, plot_imputation

2. trend_seasonality:

• plotters.py: plot_time_series_with_change_points, plot_trend, stl_plot, seasonal_plot, plot_periodogram

3. feature_relevance

• plotters.py: plot_feature_relevance

4. forecast_analysis

• plotters.py: plot_forecast, plot_backtest, plot_backtst_interactive, plot_residuals, qq_plot, prediction_error_plot, plot_metric_per_segment, metric_per_segment_distribution_plot

5. eda_utils

• plotters.py: plot_correlation_matrix, cross_corr_plot, sample_acf_plot, sample_pacf_plot, distribution_plot, plot_clusters

b) All the other methods should be placed in the utils.py file of corresponding folder c) Improve the imports in the notebooks if necessary
