Implement the logger functionality

[billp]

Description

A user will be able to log hours by providing ticket ids and optionally durations by using a specific syntax.
He can also specify a date for hours to be logged in different date than the current one (today).

Command

bin/jira-logwork log [ISSUES_WITH_DURATIONS] --date [DATE]

Arguments

ISSUES_WITH_DURATIONS log argument (Required): It's a string which contains comma-separated issues with optional durations and start times. To clarify things a little bit, lets say a user enters the following command:
jira-logwork log ABC-123=10:00|1h30m,ERS-52=1h,ESS-312,EF-4123 --date 23/06/2020

The parser will execute the following steps:

1. Splits the ISSUES_WITH_DURATIONS string to separate issues and get their options (if any). It uses comma separator(,) for issues and pipe separator(|) for options. In our case it will create the following table:

jira_id	start_time	duration	adjustment_mode	converted_duration
ABC-123	10:00	1h30m	fixed
ERS-52		1h	fixed
ESS-312			auto
EF-4123			auto

2. Fills the missing values by making conversions. The final table will be the following:

jira_id	start_time	duration	adjustment_mode	converted_duration
ABC-123	10:00	1h30m	fixed	5400
ERS-52	11:30	1h	fixed	3600
ESS-312	12:30	2h45m	auto	9900
EF-4123	15:15	2h45m	auto	9900
TOTAL	-	8h	-	28800

It takes into account the configuration params given in configuration step. In this example, they are the following: shift_start: 10:00, shift_end: 18:00
