Filter/search functionality

[Ubiquitine]

Hello, It would be a nice thing to have a filter/search functionality.
I'm using K9s on daily basis and one of the key-features a like is ability to filter resources by using "/" shortcut.
This really helps to navigate and find the right resource much faster.

Another thig, is some resources like ec2 instances, VPC and subnets don't have Name displayed. I know that in some cases this Tag is not mandatory, but adding Name helps to identify the resource better.

+1 to this. The filter functionality is one of the most compelling things about k9s. Might be open to contributing.
