No indication that a user is not permitted to create public channels

[TheReal1604]

Description:

I revoked the permission to create public channels for certain user groups. The issue with this is, that there is no indicator that the user is not permitted to create a new public channel, the button is just not clickable. (and nothing happens)

Server Setup Information:

• Version of Rocket.Chat Server: 0.62.2
• Operating System: Ubuntu Server 16.04.4 LTS
• Deployment Method(snap/docker/tar/etc): docker
• Number of Running Instances: 3
• DB Replicaset Oplog: YES

Steps to Reproduce:

1. Revoke permission for users to create new public channels
2. Try to create a new public channel

Expected behavior:

There should be a screen that says the user that he is not permitted to do so..

Actual behavior:

Nothing happens.

Relevant logs:

Remark: the button to add a channel from directory view also seems to be impacted.

Adding a quote from there:

if I disable the creation of channels for some user group, the button to create the channel is not present in the main menu but it is still present in the Directory menu allowing a user to try to create the channel (but failing) and (worse for me) to see the entire list of users. I hope I explained it better.

We will fix the private/public channel switch behavior on the Create new channel page, check for permissions to show the create channel button on Directory and create permissions to allow users to use the Directory feature.
