Add the ability to subscribe on Jira issue blocking another issue or being blocked by another issue
In Jira - Mattermost plugin, there is no way to subscribe on issue link updated to sepcify issue is blocking another issue (or being blocked by another issue).
For agile development, subscribing on issue blockage is an important feature. Currently there is no way to subscribe.
In jira this is represented as a link, but in the subscription form, there are only Epic links available.
