Extending certificate table with Issuer and Subject columns.

This commit introduce two new columns on certificate table.
It should help user to differentiate multiple mTLS certificates.

Date format was changed to 'medium' one to accommodate two new columns.
Small corrections were made to action button paddings to make the icon better centered.

Tested: GUI tests were done on Chromium v74.0.3729 browser. Desktop and mobile version.
