Add error information to Mattermost CR status

[dimitraz]

Hey, apologies this took a while, I've been a bit busy! PR is here: #253

[Szymongib]

@dimitraz You might want to use docs/examples/mattermost_simple_anywhere.yaml. It is basically the same but it uses a new CR. I think we want to add this feature only to Mattermost CR from v1beta1 version as we no longer extend the old ClusterInstallation.

Ah yes sorry, that's the one I've been using, I'll continue with that then! Thanks

[dimitraz]

Hey! I would be happy to take a look at this for hacktoberfest if it's available :)

[Szymongib]

Hey @dimitraz, thanks for your interest!
It is available, feel free to take a look or ask for more details if something is unclear.

[dimitraz]

@Szymongib Cool thanks, will do!

@Szymongib Just a quick question, what CR example would you recommend deploying for dev? At the moment I'm using the one in docs/examples/simple_anywhere.yaml but was wondering what you would typically use!
