Allow processlist columns to be selected in config file

[ghost]

I do not need all columns of the processlist. I would like to select the columns to be shown in the config file.

CPU%, MEM% and command should alway be displayed.

Other column could be disabled by configuration. If a column is disable:

• stats related to the column should not be grabbed
• sort is not possible for this column
• filter are not possible for this column

Warning:

• should be compliant to both thread and program mode
• take into account: PPID not displayed? #1626
• Related (for the WebUI) How to configure/format/reorg the web-server display? #1515

Example in the Glances configuration file:

[processlist]
disable_stats=io_counters,cpu_times,status,num_threads,pid,nice,username
