Create plot support

[asorici]

Why

We need to have exploratory plot support in order to visualize the results of our analyses.

What

Implement support for at least the following types of graph:

• boxplot view per hour, where the data for each box are the water consumption values for that given hour for all recorded days
• concatenated view of all water consumption for a given costumer (i.e. concatenate all rows in one single large timeseries - useful for our seasonality analysis)
• plots for timeseries decomposition - view trend, seasonality and residual components

Notes

To make visualization interactive, we will be using the plotly library (install via conda here).
