Memcache issues

[PatelUtkarsh]

Running wp command throws this warning.

Example: ee4 wp test2.com cache type

PHP Warning:  Module 'memcache' already loaded in Unknown on line 0
Default

Also, Memcache seems to be not configured properly, See below:

$ ee4 wp test2.com cache add foo 1
PHP Warning:  Module 'memcache' already loaded in Unknown on line 0
Success: Added object 'foo' in group 'default'.

$ ee4 wp test2.com cache get foo
PHP Warning:  Module 'memcache' already loaded in Unknown on line 0
Error: Object with key 'foo' and group 'default' not found.
Failed to run with the arguments provided: wp test2.com cache get foo

Usage:  ee4 [Global Options|Commands]

Subtasks:

• [x] Config memcache
• [x] Fix memcache error PHP Warning: Module 'memcache' already loaded in Unknown on line 0
• [ ] When wp-cli command fails with error it should not show ee4 help.

The wordpress image used by ee4 is being built using this Dockerfile

So changes need to be made to this Dockerfile.
