Describe the bug

User is unable to override the default configuration forinit_options becausetbl_extend is used instead oftbl_deep_extend here:

If deep extend was used, user could provide a subset of extendedCapabilities to be overridden. As is, the entire table is replaced with the user config, meaning the user has to redefine all defaults to change one value, for example

Steps To Reproduce

1. provide

require('lspconfig').jdtls.setup({init_options= {extendedClientCababilities= {...    }  }})

2. The entire default table will be overridden

Expected Behavior

defaultextendedClientCapabilities table is merged with user configured table
